I have a 99 Bonneville SLE with 88000 miles.
Recently purchased so I don’t know the history on the car.
The problems are as follows;
*Vibration that can only be traced to the drive axles or transmission, unknown.
*Hard hammering during moderate takeoff from dead stop, like the tires are slipping and jumping. Occasional, but I will not do a WOT takeoff, too scared.
*Also occasional, Odd shifting, like it cannot make up its mind.
I am not a fan of dropping $1000 plus at a shop just to have them spend an hour with my car when I can pull the tranny in 3 hours.
Any Ideas on what this is?
I am thinking of pulling it and rebuilding it, but if my problems are electrical I will be wasting my time.
Mechanical doesn't scare me, electrical does.
Anyone had and fixed a simular problem?
