For the longest time I thought I had 3.73 rearend gears. But I've since found out CUCV blazers came with 3.08s. I started checking things out, used the calculator on Randy's and what matches up perfect with my RPMs at various speeds is 3.42s in the rearend. This is true even with the tranny in 2nd. The only thing I haven't done is pull the cover and count teeth. Here's what's occupying my mind. Could it be that my blazer actually came with 3.42s. Or is my tranny slipping that bad? The only other thing I've noticed is that when the tranny is good and warm, I have to give the motor some throttle to get it moving in reverse. When you first pop it in gear, it is just like it's still in neutral. I've been keeping an eye on the fluid and it is nice and red. I know that reverse and direct drive share clutch packs. Basically I can either drop $1000 on the tranny or new gears on the axles. What are the opinions.
