Transmission case sleeves, ZF 4HP22/24 EH valve body questions

[Annddrriy]

Yes it missing. I mean the bigger part of the breather goes to manual gear selector side ? Or other way will not go.

[shogun]

Yes, the ETK shows the bigger parts of the breather valve towards gear selector side and the cross section I linked above looks also like that. See ZF 4HP22 repair manual 2 cross section 4HP22, larger part of breather valve goes towards manual gear selector side, see page 83 drawing 82 168, there the extension housing is shown in detail where the breather valve is mounted and there you can see that there is only one possible way to install the breather valve into the extension, other way round it will not fit = larger side of breather should be towards manual gear selector side.
Install the o-ring onto the breather valve and then install it into the extension housing, from outside of the extension housing use the circlip. It is also mentioned always to use a new security clip ZF p/n 025034 BMW 24111216347 when installing breather into extension housing. https://www.scribd.com/doc/254865544...-Repair-Manual

It was fallen on top of the input shaft and got damaged a bit I clean it up and going to put another one good from another transmission last time mechanic could not fixed properly and when I was installed another used transmission by touching breather got damaged. What will happen if breather installed another way ?

What will happen if breather installed another way ?

as I explained in above post, other way installation will not fit = larger side of breather should be towards manual gear selector side.

[Annddrriy]

Yes I installed as writen in ZF 4HP22 repair manual 2 cross section 4HP22 larger part of breather valve goes towards manual gear selector side and works good not overflow oil anymore through breather.
Do you know what is oil viscosity takes ZF 4HP22EH at 210 F ? Thanks !

[Annddrriy]

The Valvoline Automatic Transmission oil has 5.5 cs viscosity at 210 F. If viscosity number increase is it better for wearness friction discs ?

[shogun]

Thanks ! Car run out about 300 km I remove oil pan to look for any wear and found some like normal fine sand on the magnet not too much but it's there. I will go with pentosin oil next oil change.

[Annddrriy]

Anyone have for sale forward gear direct hub part number 575 ?

[shogun]

part number? find the correct ZF part number and google search with it. For example here https://go4trans.com/transmission/4hp22/

[Annddrriy]

Do you know what small screw in transmission oil pump housing for ? If one bolt missing near small screw in transmission oil pump housing it can build pressure in forward gear clutch drum and brake direct hub a part ? Thanks in advance for your answer !

[shogun]

which one? Here is a Oil Pump Kit ZF Automatic Transmission. This kit contains pump housing and gears, housing o-ring, 8x bolts (M6x28mm), dowel and shaft seal to suit the 4HP22 ZF auto transmission.The dowel and shaft seal are pre-fitted to the pump housing. https://www.allfourx4.com.au/Oil-Pum...ket-1043298089
there are 8 bolt holes and the bolts are shown here http://bmwfans.info/parts-catalog/E2..._lubric_system

[Annddrriy]

Look at post #594 there is picture of the automatic transmission oil pump housing and there's one bolt missing near by small screw between two bolts you can not miss to see that. That small screw can be unscrew with flat screwdriver.

[Annddrriy]

Sorry about small screw that is not small screw its look like small screw. This is groove of oil pump of o-ring side and facing out like flat screw.

How to flash bmw E32 automatic transmission tcu ?

Annddrriy : How to flash bmw E32 automatic transmission tcu ?

Your E32 735 M30 4HP22 still has the older M1.3 DME and old TCU with EPROM, not EEPROM. EPROM cannot be flashed. It must be replaced by another EPROM which you would have to program new.
Early Engine and Transmission Control Modules used EPROMs (Electrically Programmable Read Only Memory device) to store operational programs and operating data specific for the application that they were used for. Since the operating program and associated data is installed at the factory during the vehicle assembly process updates could not be provided for vehicles once they were programmed and left the factory floor.
In order to install a new or updated program (DME or TCM) the module needed to be replaced. Eventually it became possible to replace EPROMs and/or update them which dramatically reduced the cost of updating a module and a vehicle.

With the introduction of M3.X & DME/ECM control modules it was no longer necessary to replace the entire control module in order to install updated engine operating programs and/or data.
At the end of 1995 new variations of DME/ECM control modules were introduced that no longer contained a removable EPROM but instead contained a soldered in EEPROM. An EEPROM is an Electrically Erasable Programmable Read Only Memory device, which means that programs & data stored on the chip can be electrically erased and replaced with new/revised programs or data. In order to erase the data on the chip a short duration low level voltage/charge is applied to a pin on the EEPROM and the stored data is erased, hence the name “Flash”. Once the data is erased new data is loaded. By using a newer technology, these control modules have the ability to be updated a total of 13 times before they need to be replaced. Theoretically an EEPROM can be erased and reprogrammed more than 13 times, BMW set the number to 13, since a point will be reached where the update being installed may no longer be compatible with the hardware of the installed module which could result in erroneous operation. If the program is not compatible with the hardware version of the module, the program used to determine the correct update for the module will indicate that the module will need to be replaced before the update can be performed. The reference to Flash programming is a result of the technology used to erase the EEPROM prior to installing a new program and or data.

The introduction of newer generation Transmission Control Modules introduced with the M44, M52 and M62 engines at the end of 1995, brought with it the ability to “flash”program this module as well. By being able to electrically erase and install a new program and or data stored on the EEPROM, it no longer becomes necessary to replace the chip to get an updated transmission program installed. The technology used on the Transmission Control module is the same as explained in the section “Engine Control Module Flash (EEPROM) Programming”.

When scanner connected to TCU it flashed for it. They do the flashing for TCU. It’s to factory specs though. One programmer can reprogram BMW E32 automatic transmission TCU from tool EETA314A-CAN Pass Thru Assistant. What it doing when scanner connected to the automatic transmission TCU. When scanner connected to the automatic transmission TCU it brings RPM up to 1900 till speed reach 90km no metter how do you press gas. You can press fuly to the floor the RPM stay up to 1900 and when speed reach 100km then RPM stay up to 2200 and no any code after scanning. When scanner not connected to the transmission TCU it shifts through all gears from first to forth and this transmission acting as 5 speed and has a code 54 converter clutch drive position switch. The code 54 coming from last gear. Also I checked what it doing with solenoids while scanner connected to the automatic transmission TCU . The scanner shuted OFF two shifts solenoids MV1 and MV2 and keeps ON lock up solenoid and pressure regulator solenoid keeps power 9.25 volts at idle and when RPM goes up then volts goes up.
This way it bypass shifting gears of turning shifts solenoids OFF and turns lock up solenoid ON. When lock up solenoid turn ON at idle it lock the converter clutch to the converter housing lightly. You can make it manualy if you don't want to upgrade your TCU simply disconect two shifts solenoids from TCU and bring power to the lock up solenoid this way you can do what scanner does.

If hydraulic automatic transmission installed how to connect accelerator cable to the throtle body ? I removed hydralic automatic transmission from BMW E23 1985 with accelerator cable and throtle body. Could not remove torque converter of rusty cylinder pistons someone remove the engine cylinder head and water went to each cylinder I just turn a bit crankshaft back and forth and could not remove 3 bolts from torque converter. That torque converter have had flex plate on the flywheel. May I use torque converter from BMW E32 1990 ?

[shogun]

probably no one has ever used an E23 1885 automatic transmission on an E32 735 1990, so that is all what you have to try and test by yourselves. Compare ETK E23 and E32
torque converter C7 p/n 24231217222 was used on E32 735 till 09/1990 from Sept. 1987. Same p/n was used on E30 M20, E34 M30, E32 M30, not on E23 1985.

[Annddrriy]

May I use hydraulic electronic valve body E9 version in hydraulic automatic transmission. Do you know if there is a hole for the pulse sensor in the hydraulic automatic transmission 4HP22 ? Accelerator cable hole I can block it with some rubber plug to use it silicone and governor valve I can removed and install sensor pulse wheel. Output shaft driveshaft yoke probably same.

[shogun]

The only way to find that out is, that you check the original ZF 4HP22 transmission spare parts catalog in detail item by item, you have the Stucklistennummer of your original 4HP22 on the metal tag of your transmission, and in the parts lists there is always mentioned for each part that it fits to Stucklistennr. ...., example only! illustration item no. 254E fits following box codes only: 1043 010 728, 739, 740, 747, 748, 749 etc pp.
Then you will know if the same hydraulic housing was used or not.

[Annddrriy]

Do you know automatic transmission pin #4 YEL/GRN wire where it goes to engine control system ?

[shogun]

It is time consuming, but you have to study the ETM, I assume = not sure from the transmission pin it goes first to the transmission control unit, and from the transmission control unit the wires go to the DME, https://shark.armchair.mb.ca/~dave/BMW/e32/ pinout of the DME and TCU are there as well as the wire colours.
Pinout TCU starts from page 2460-a
page 45, figure 37 shows for pin 4 the color brown and that is from the output sensor, but it is also mentioned that colors may vary http://www.bmwe34.net/E34main/Troubl...ch%20Guide.pdf
page 2460-b of the ETM shows the pinout of the transmission control unit, pin 27 = E=Eingang = input shows output speed n-ab (-), connection: gearshift unit, so that means the output speed sensor in the transmission sends the signal to the transmission control unit pin 27.

[Annddrriy]

Tha is probably for 750 series with EML control module. Anyway. Thanks for answer. I am cleaning valve body zf4hp22eh there is one spring I do not know what size I should put it on. The technical servise information written spring diameter .67" in lower rear 3-4 shift valve ?

[Cactuar]

Annddrriy when working on your transmission did you have to order gaskets for it? I'm trying to source a separator plate gasket for my 4HP22EH valve body and no one can source it here. I even tried Eurowa in Montreal and they couldn't provide it. The only options are individual gaskets from Cobratrans or an overhaul kit from Rockauto. Both options are outrageously expensive for what is essentially a thin paper gasket.
