Good morning all!

My '86 Auto Vanagon Westy with 127K just started
hesitating/bucking/slipping? when pulling off from a stop.  My analysis
so far is that it only occurs when just starting off in 1st gear (1st to
2nd and 2nd to 3rd are fine).  There is no hesitation when starting off
in reverse.  There is no hesitation when I rev the engine in Park or
Neutral.  A/T fluid is between the high/low marks after warm-up and I
checked differential gear fluid last night and was fine.  Both A/T fluid
and Diff gear fluid were changed less than year ago.  The bell housing
area is darker than the rest of the transmission as if it has thrown
minimal amounts of fluid around, but not enough to notice on the
dipstick.  My symptoms may be moot, considering that this transmission
has not been rebuilt, but other than the starting off in 1st gear issue,
the original trans and engine run fine.

Thanks

Kevin
