alright i have a stupid question. i manged to find an uuber rare transmission, from a celica st165. i am of the understanding that they are basically the most identical to the rav4 transmission of all the alltrac cars, being first generations of both and therefore using the same 2nd hand transmission (caldina).
im wanting to swap out the center diff, the celica center diff in the st165 trans is a viscous coupling LSD, so its a proper high performance center diff that gives a lot more power to the rear thanks to an even and reliable power distribution, rather than the stock open center diff's tendancy to power the front wheels first when conditions are slick.
i have the 5spd with center diff lock, which is great if youre bombing through deep snow and mud, but the rest of the time i want it to be more solidly planted and more predictable on slippery roads (sometimes its all rear wheels, usually all front, making it kinda sketchy, our roads are solid ice 6 months of the year or more here)
a friend of mine who is a mechanic figures it will be "geared differently" but i was under the impression that the center diff's only purpose was splitting the power front to back, im 90% certain there is no drive gear in the center diff, and hes thinking of a transfer case in a 4x4, rather than a center differential, am i correct here?
but the overall point here, is can anyone tell me if this peice is going to go into my rav4 trans? obviously one option is to swap the whole transmission, which i would really rather not do as i like my rav4's gearset as is, and for all its compatibility, i dont think its a direct swap all around (clutch, cv shafts, etc.)
