I'm currently looking to sell my 4R70W from my mustang and I have a guy with a 4th gen E-series van who needs a new one. His car has the 4.2L V6. I'm wondering if mine will fit in there without any issues. I read that some use the AODE and some the 4R70W. Would it be safe to run a 4R70W instead of the AODE even with the slightly different gearing? Would this cause problems? Does anyone know if the bellhousing on the 4.2 will match up to the 4.6 since the bellhousings on the AODE isn't removable?
