Questions & Answers
Questions: I have a 1962 Truck. 226 Super Hurricane, 4wh drive. I've noticed that there are different T90 cases. T90A, T90C, T90J. I have a spare T90A case. Will this kit Fit the T90A case that I have & be a direct replacement to my current combination? I thought I'd rebuild this case, instead of taking the transmission out of the jeep & rebuilding it. Thanks

Good news is all T90 cases are interchangable. The T90A was the standard ones used with 4 cylinder, T90C was the gearing one and T90J used in Truck/SW. But they all will interchange parts.

Questions: Can a T-90 be fitted with a first gear syncro? If not, what transmission can I substitute that will give me a first gear syncro.

I had the same question for my 68 cj5. I found a T14 that is synchronized in all forward gears as well as reverse. Very hard to find parts for. I believe they were only used behind the 225 v6 from the factory. It was an easy change with the case bolting up to the T18 case and 225 bell Housing.

T90K is the part number for that. Or we do have complete rebuilt transmissions as well for both.
