XT6 automatic transmission 4EAT AWD - 3.7 gear ratio

XT Turbo Manual transmission FT4WD - 3.9 gear ratio

 

I'd like to have the manual transmission with a 3.7 gear ratio output like the automatics. Will the front diff of the 4EAT swap into the XT Turbo manual FT4WD trans.

 

how could i find out, what would i be looking for if i took the trans apart?

From what I understand, the final drive ratio on the automatics is not really 3.7, but rather a ratio that when combined with the tranny gearing yields a 3.7. Regardless, I believe that the mechanicals are not compatible.

 

You could look for an RX tranny. Or, I thought for sure that my turbowagon has a 3.7 rear ratio, but it is not here to confirm or deny my questionable memory.

so there are 3.7 ratio manual transmissions out there? thanks pat, i'll do some searching and maybe start another thread.

 

a 3.7 ratio will will get better gas mileage than a 3.9 right?

getting a 3.7 manual would be the best way to go.

 

after reading up on trans differences there's no way swapping the auto diff into the manual would be possible.

Yes, there are 3.7 ratio manuals. The LSD rear end only came in 3.7 (at least for EA82), and many of those cars were manuals. (After all what's the point of an LSD with an automatic? )

 

As my memory congeals (sleep-deprivation...), I just remembered that my project wagon (which has an LSD) is a turbo with FT4WD S/R 5-speed. So, yes, they are out there in both RX and non-RX applications.
