1988 integra auto shift 90,000miles:
When the engine is cold, say overnight, when I shift the gear form Park to Reverse, there is a very big jerk(in fact the whole car jerk).
The same thing happens when I shift from D to R and R to D backforth.

But this "sharp jerk" is a lot less serious when the car is warm.

I was thinking if this is due to transmission fluid being low,when the car was not driven overnight, the fluid levels drops down and some of the gears are not coated with fluid. Any ideas?

 

had a 89 integra with the same problem. i ended up rebuilding the tranny twice.

 

Should I choose an Acura dealer or Honda dealer to do it for me, Acura is kind of pricey.

 

Mine been jerkin a while in my civic, it ended up breaking on the Freeway. I thought it was nothing, maybe the Fluid but i was dead wrong...
