I just had a few questions before I start spending cash, cause I'm considering going with a th400...
-Will the all the shaft spline counts be the same as in a th350?
-Is a th400 short tail = to a longshaft th350?
-should I even invest in a th400 to begin with?
-has anyone had any experience with "raptor blood" atf?
-should I go with an integral or external atf cooler or both??
-does anyone want to donate me a transmission or give me a good deal on one?
