Transmission Compabality

[partiesplayin]

im am confused on the compatability between the years.. is there a clear guid for the 2g awds?


95-96 97-99 awd 5speed transmssion's, what exactually is interchangeable?

transfercases, diffs, gears......?? i have found nothing that clearly spells it out so to speak.

also only information i have found on useing a jdm tranny is changing out the ring and pinion gears to change the final drive to match the year of car you want to install it in..

I just put a 98 gsx trany in my 92 awd talon with no problems

All years of 1g and 2g can interchange with their respective body styles (for example: a 90 GSX trans can be swapped into a 94 Tsi or a 95 Tsi can be swapped into a 99 GSX) Now as far as switching generations, a 1g can use a 2g trans but a 2g cannot use a 1g trans. (example: You can swap a 95-99 trans into a 90-94 but you cannot swap a 90-94 trans into a 95-99) make sense?

yes i understand, the reason it cannot be done i herd is because of tranny mounts. the 2g transmission has 3 tranny mounts and the 1g tranny only has one which is why you cant usea 1g tanny in a 2g becasue you need 3 mounts to hold the engine in place on a 2g.

6 questions below if i can get these answered i will be good to go


why do i keep hering that you have to have the same transfer case as the year tranny you are using?

if i have a damaged 95awd tranny can i use internals from a 97-99 to repair it.. or if i have a jdm tranny can i just use the gears and differentials from it ?

Also if i have a jdm tranny and change the ring and pinion gears to change the final drive ratio, then what transferr case do i use, a 95-96 or a 97-99?

what is the difference?


And are the internals iterchangable between the years of the 2g transmission?

i know all about spline counts need no education in that respect, but i keep hereing different storys, if you use a 97-99 tranny you have to have a 97-99 transfer case. why?

these are the questions that need to be answered.

Can someone answer the questions above? I'm in the process of looking at a 91 A/T with 21 spine tcase for my 94 6/4 combo. If it works I will be buying the tcase as well...
