My 94 GMC Sonoma jumps a little when driving but only at 60 to 65. This is the 3rd trip I have made across country in her. Everything else is fine. Just changed the oil and trany fluid 2 months ago. I
what you mean by "jumps a little"? (steering wheel vibration?) and 60 to 65 kmh, or mph?
Jerks foward a little I guess at 60 to 65 mph. No vibrations at all. Other then this no other problems
sounds like a tranny issue, i think your saying that the tranny is slipping a bit.. idk, my first instinct is to check tranny fluid and if good, add a tranny fluid additive (like lucas additive). it wont hurt.
I'm hoping its not that cause my dad and I rebuild the tranny 3 years ago. I'll try the additive, hopefully she just needs a little kick... I was thinking it could be the weight she's carrying this time with the ladder rack and shell added.
