My 94 3.0 Runner is on the road and runs reasonably smooth except when shifting from Park or Reverse into Drive. Almost jumps when put in gear. Doesn't seem to do it when going from Neutral or Park into Reverse. Idle is about 900 RPM.

I recently rebuilt the engine, but have done nothing to the transmission. I have done a number of searches on the various forum in an attempt to answer my questions, but have not found enough info for the following quesitons:

1. Given that the runner has 177K miles on it and I don't know what maintenance has been done to the tranny, what does everyone recommend doing as preventive maintenance? Fluid flush, filter replacement, fluid exchange, etc.? I have hear on more than one occassion that a complete flush is not recommended as it may dislodge buildup and clot jets/ports.

2. What ATF fluid is recommended?

3. ATF fluid is low on dipstick (below FULL mark when hot). Would this be the culprit for the sudden lunge/jump when moving to Drive?

I know little to nothing about AT's and need advice.

Thanks,

Aaron
