Ford Repair: c4 ford transmissions, ford transmissions, mustangii

Question
I own 5 transmissions. All are c4/5 transmissions.I have 3 are case fill and two are pan fill..The case fill transmissions two are from 6cyl mavericks and one is from MUSTANGII with a 302.Is there any differences on the inside of the transmissions between the 6 cyl vs the V8.Can I just trade the one that is broke its a case fill and replace with a 6cyl case fill..My case fill v8 mustangII trans is bleeding behind the pump,and I actually want to rebuild them and want to make sure all the trans will use the same rebuild kit.thanks,

Answer
Tom, all C-4 transmissions are not alike.  There are many similarities, but you will need to know a little more about each of them in order to rebuild them.  A transmission shop would be able to help you find the right parts.  I hope this answers your question,    Jason
