Hay so my issue is with my 1994 Jeep YJ 4.0 AX15 Tranny as the title says my Jeep jumps or bucks sometimes in 1st and 2nd but its so bad in 4Low I dont use it when off road because Im sure something will break. So I need help figuring out whats going on Ive looked for a thread that talks about this but no luck .
So Any Help Would Be Great
mine does it too in 4lo. if i just barely tap the throttle it sets you back in the seat pretty damn hard. it's because you are in low range that it is doing this.
Ya its not that I found out it maybe an motor or tranny mount or TPS (throttle position sencer) the Jeep has 200+ miles on it but thanks for the help anyways.
Broken drivers side motor mount in my Xterra did the exact same thing. Truck would jump and stall in first and all gears in 4 low.
Replaced both motor mount, no more problems.
