    I need to replace my TH350 transmission, I have a 205 t-case, I know that my transmission output has 27 splines and uses a drivesleve to mate up to the t-case. My question is does a TH350 for a 203 t-case have the same splines ? If so will it bolt directly to my 205 ? Or will I have to find a TH350 that is for a 205 t-case ?

    Anyone out there know about this ? Thanks

    The 4wd version T350 will have the same (27 spline) output for either the 203 or 205.

    but the transfer case adapter will not work. you will need the one that is originally for a th350+np205 setup. Does your transfer case that is sitting around have the adapter and sleeve?
