The trans in one of my T&Cs had a bad case so I found another T&C that had a trans that worked. This summer I pulled the axles out and last week I pulled the trans out and put it in the other van. after installation the van will not move. I replaced the filter and fluid but no luck. I also put the TCM that came with the replacement trans in. When I put van in gear the engine speed changes slightly but thats all. Anyone know what maybe going on?
