Hey guys got another problem the trans when car is warmed up when i put her in drive she ingages hard like a good jolt it does not do it in reverse or anyother gear changed fluid and filter it will do it when its cold only when she is at normal aperating temp and just replaced TPS, Coolent sensor and O2 Sensor what could it be

[Jchiasson]

...um...
So when exactly does it do this? Cold or warm?
The items you mention, TPS coolant o2, really have nothing to do with how the transmission engages.

When it is warm at norm temp only in drive not reverse or any other gear

Drive, shifting gears or only just putting into "d" on the floor part... when was the last time you had your transmission fluid changed? how many miles are on the vehicle?

[jftaylor]

Only when i put it in Drive its rough only when its at norm temp while driving trans shifts perfect its when i put her in drive changed the fluid and filter one month ago another member said to check the engine mounts or could it be something else

that's not entirely true the tps, coolant temperature sensor and the o2 sensor all can indicate to teh ecu that the car is still in cold start causing the engine to run rich adn idle at a slightly higher rpm which could cause rough shifting. i would suggest chcking the connections to all these sensors and then reseting the ecu this may help.
