Now, I just want to be sure of one thing before I yank the transmissions out of these two cars and attempt the bellhousing swap. What is the difference between a C4 and a C5? I've been reading posts about people swapping a C4 for a C5 and vice versa. I guess, since i'm not sure if the trans in the newer car (pan fill, push in modulator) is a C4 or a C5, will the bell swap to a trans that I know is a C4 (early 64 model year, case fill, screw in mod)?
Thanks for any help clarifying this.
If it is slipping in second and not in any other gear yes a front band adjustment would be in order. If it slips in reverse but is fine in all the forward gears then the rear band would be the adjustment that was necessary. If it slips in second and/or high then it would be the forward clutches that were bad and a rebuild is in order.
