Auto tranny swap?

Post by Danteandsoob »

Would it be possible for me to swap the '93 3.90 automatic, to a 4.11 manual, but still keep it automatic?

I know it sounds stupid, but I was just wondering.

What exactly you're asking for isnt clear. Do you mean using the 4.11 final drive ratio from the differentials in a manual car to make you automatic car have a 4.11 FD? If thats the case, you can use the rear differential from a manual car, but you need to find a 98 or older automatic transmission with the same 4.11 ratio since the front differentials are built-in cannot be swapped between automatic and manual transmissions.

If you want to swap another automatic with 4.11 final drive ratio, you can do that as long as it's a phase 1 4EAT. You'll also need to swap the rear diff to match the 4.11 final drive ratio.
