Well the application is for of all things a 1970's Jeep Wagoneer, from what I gather all the TH-400's (I hope that holds as I still have to open mine up) have the passages needed, but I will have to check on the AMC pattern Th-400 Jeep used, I have more GM than Jeep parts in the case now (I never found a AMC/Jeep case vs. BOP/chev case differance) so far other than the bellhousing patterrn, I hope that holds true with the SP passages. So I beleive I am looking for a 13" low -> medium stall ratio converter vs. the medium->high 12" ones tha go fast guys like/need.
I am in Richfield MN, I hope to have my Sh** together enough to know exactly what I need for the Switch pitch soon. (Still on the steep part of the learning curve) The plan is AMC/Jeep TH400 case (on the shelf worked good/low miles, had the usual 30+ year old leaks, when pulled from my Jeep) Rear output GM 203 short 32 spline output shaft (for GM 241 T-case) Front : 13" SP converter (Need) SP input shaft (Need) SP pump (Need) SP (or the later Emission) 2 prong case feed though connector SP (or later) Wire harness pig tail (nice to have) I think that is all the tranny stuff. (Other than the normal rebuild kit) DansGS, C.Rob I'll shoot you a PM to see if your stuff is applicable. Trying to keep it all just like Jeep built it, (From the random parts bins of every other manufacture ) Thanks Mike D.
