Will this fix my problem with my Camaro (Transmission related, and suspsension?

Question

I recently had a 200 trans in my 1977 Camaro with a 350. I got the motor to idle great and it sounds amazing but when I went to drive it first gear was a little balls less but then 2nd and 3rd it would just BOG its way up. But then at random times the *** end of my car would jerk violently and scare the h**l out of me. I am putting in a TH-350 right now, but could my problem lie somewhere else?

Also for extra credit the rear end sags. Do I need new leafs, bushings, or something else?

Answer 1

seems like you know what your doin ..why ask simple questions like these..you know what to do

Answer 2

Springs cause sag. Change bushings as well. Trans is not the problem. Good luck.  

Answer 3

The TH200 is a bit gutless (small internal parts) or light duty for a 350ci engine ,  it may need an overhaul . myself I would install a lockup TH350 to keep the lockup converter for fuel milage or nonlock-up for mild performance .

While the drive shaft is loose turn the wheels and pinion input and note how smooth or ruff it is.

Does it have the mono leaf springs or spring pack ?

The car is 30 years old and I'm sure the springs have saged and could use a new set front and rear. that will help the handling and ride drasticly . or you could get a set of add-a-leaf and help some for awhile for about half the price and the same work.
