    e28 4hp22 trouble

    Hello, I have a problem with my e28 with a m30i35 engine from e32 with motronic 1.3, I installed the automatic transmission 4hp22eh by myself from e28 535. this is an electronic automatic transmission with 5 solenoids and a sport mode.
    problem
    1 - hard switching P-R and N-R, but not always 7 out of 10
    2 - at a low speed, about 60-100 km.h when the car is in 4th gear when the accelerator pedal is reset, I get a knock or jerk , this also does not always happen. but it only happens in 4th gear
    can you help me or advise me what to do?
    oil, filter, cardan shaft, engine mounts are all in good condition

    first of all check the solenoids in the valve body and the speed sensor, details about the pinout of the plug here , download the file http://www.bmwe34.net/E34main/Troubl...ch%20Guide.pdf
    4HP22 has only one speed sensor for output, the input signal comes from the crankshaft position sensor

    here a ZF 4HP22 problem was solved by changing the transmission control module, old one was defective https://www.bimmerforums.com/forum/s...leshoot-solved

    on your site there is a gear box mechanical finding, it says that if the reverse is turned on hard, it means that the problem is in the damper B . It is defective. could it be like this?

    transmission control test measures (http://www.europeantransmission.com/...n_zf_86-88.pdf )
    i passed this test with my car except td/tr signal (can't measure) and Ti signal at 08-1.2 volts tolerance i get 6 volts, at 2.8-3.2 volts tolerance i get 7 volts
    maybe it's due to the fact that I have a 1.3 motortronic?
