The Sport Trac I'm looking at is a 4.0 Automatic. I can always source a 5sp manual if the automatic doesn't work out. The manual Ranger 4x4 tranny should work and there are plenty of them out there. I'll use a BHW harness all the way to the OBD port with mods where required for ABS,IMMO, etc. It's a 2003 so shouldn't be too bad. A friend of mine converted an 08 F150 to a 606 and retained the Ford automatic and TCM. We both used aftermarket ECU's in our conversions. I should be able to use the BHW ecu since I have the entire donor car. Doubt there are any aftermarket ecu's for PD diesels and I want to retain VAG interface if possible. If anyone knows of successful conversions that didn't use the vw ecu, let me know.
