First is fine. Second bucks around like a wild bull....

Im having an issue with my 87 GN. First gear is absolute fine perfect idle smooth ride. But when it shifts into second gear it starts to shake back and fourth. third gear is the worst practically giving you whiplash... i dont know what it is at all.. no plumbing is undone maf seems fine etc... what could be happening?

I'll put my money on a bad TCC solenoid in the transmission. Common malady and an easy fix by just dropping the pan.

really thats it? easy fix right on. THANKS!

anything else engine wise that could be making this issue happen?

 

[MeanBuicks]

As you've described it, not likely.
