Please advice. My 94 Max with auto trans developed significant gear shift "jump" when transmission cold for the first couple of minutes. After warming up gear shifting is smooth. I have around 10K miles on trans fluid. Anyone has ideas?

 

Could be your throttle positioning sensor, but buy an OEM sensor from nissan (not a stupid aftermarket one)..

 

Eric,

Thank you. Where the throttle positioning Sensor is located?

 

Um that's pretty normal, read through older posts and you'll see that it is normal for these trannies to do that when cold
