transmission issue

[bigbody7]

hi guys, lately i been having a problem with my tranny. i noticed when trying to merge with traffic the car wont switch to over drive but if i move the shifter from D to 4 and then 4 to D she will shift. some days she shifts no problem.all other gears are nice and smooth, no delays. oh 95 740i with 80,000 on transmission. transmission was serviced 7 months ago when it was installed. can someone tell me where to look.

Was the torque converter changed also?

I was wondering if the correct fluid was used. These are picky.

+1 oil level and could also be a speed sensor

[bigbody7]

replaced the converter with the one i came with.
i will change the fluid and make sure its full, but how do i kno if the speed sensor is bad

[Edwin NL]

have an indy or dealer check the senors with DIS
No need to swap fluids yet just fill her up and see if that helps, if it does then swap fluid

[bigbody7]

check everything and even cleaned the sensors with electrical cleaner. now its starting to act up more often, i also am starting to hear a whirling noise. is it possible its the tranny filter

[Edwin NL]

Whining noise is low oil and could be aftermarket filter

[bigbody7]

well fluid is definitly full cause when i pulled the filler plug off the fluid was dripping out and thats with the car cold and leveled. should i change the filter and see what happens? this thing is crazy cause if i drive slow it will shift fine and as soon as i get on it will downshift but wont change gears unless i bring the shifter down to 4 and back to drive

stupid question, but are you sure your A/M button isn't stuck in M?

[bigbody7]

100% sure. im gonna change the filter and see what happens

ditto. spilled coffee on console and even after it was clean would do the same thing for weeks until switch dried out.

you kno my son spilled a mickey d's cup a couple of weeks ago but still after the tranny was fine i did notice when i bring the shifter down to 2 i gets really stiff. maybe i should pull it up and clean with electrical cleaner or somethin

[bigbody7]

well today i have had no problem with the tranny. the car has been shifting fine all day. i have not did anything different to the car. just out the blue its perfect again. any clues???

Gremlins.
