I need to have my 4T60 transmission rebuilt since the seals are worn out... The 4T60 has a final drive 2.84 and chain ration 35/35. I still have my original 125C with 24K miles on it which has the 3.33 final drive... Since the rebuild is necessary on the 4T60, can I take the final drive and sun gear from the 125C and use it in the 4T60? Are they compatible? I'm not interested in changing the chain ratio.
