I replaced the oil filter on transmission and Dextron iii oil. It goes in D first to second. And revers. I can drive it hard in second not even a sign that it want to shift. It is if it only have two gears. And I did a diagnostic on it. And that told me TCM transmission control module communication error with vehicle ECU. And I have a fault code on speed sensor . And a PCM power train control module. Trouble code.

this is something a mechanic has to track down it is a CAN BUS problem with the TCM to PCM not reading each other like it should if you just replaced transmission look for wires pinched or broken wait until that is fixed before replacing speed sensor because it may have something to do with it.

Have some one coming tomorrow to look. Gearbox guys tell me it is inside the box. I also had the solenoids tested and valve body cleaned. still thinking it is electrical. I think you are right. Maybe must give it a match and burn the thing.

I bought the car two weeks ago. Gears got lost due to a dirty filter. that is why I replaced the filter and oil. I had no gears. But now I have. Only reverse, first and second.

I f you mean relearn they do that as you drive we have no info on that model as it's not in US the info I gave you was pretty much general info. on a computer you can erase the codes but that is about all if it needs to be reprogrammed a mechanic has to do that and it's usually at a dealer unless it's just security to be reprogrammed.
