Hi Olds Fans, I have a 1996 LS 88. Sweet car, 115k on it. Runs
perfect but I am noticing a bucking when going into 4th (OD Gear) at 45
MPH & trying to accel to highway speeds.
Seems like the engine is not reving enough & the car starts to buck
because the rpms drop from going into 4th.
If I toss the shifter back down to Drive. the revs come up & it
accelerates with no bucking issues.
What could this be?
not sure if it is the same type of tranny or not, but i had an '86 olds 88
that had the 3.8 HO, with the 4 speed tranny.
when it got to about 105k miles, i noticed a weird "bucking" sensation that
started at highway speeds.
about 3k miles later, I lost 2nd and 4th gears in the tranny and junked the
car.

It might just need a tune up. Sometimes misfires become more
pronounced in high gear at low rpms.
