Kind of a long post, so get a cup of coffee. I know this kind deals with a V-6 Mustang (I posted in that forum as well) but the people here are a little more knowledgeable.
I am having a problem with a AODE tranny in a 1994 Mustang with 3.8 engine. Just bought it from somebody and he told me the car would not shift out of 1st gear. He said he checked the fluid level and made sure it was full. I confirmed that it was full. Still, stays in first gear when put in Drive. Anyway, bought the car and took it home on a trailer. I pulled the pan off the transmission and replaced the filter. I also drained the torque converter to completely change all the transmission fluid, which has probably never been done since Ford put transmission fluid in it. I used MERCON V tranny fluid. Well, took it out for a test drive. When put in Drive, the car will not shift out of first gear. I can put it in 1st and then manually into 2nd gear, but the car will not go into 3rd or overdrive at all.
Well, went and bought a OBD II scanner from a local parts store. I had been wanting one anyway, so now was a good time to buy. Did the scan and there are no codes in the system. That is good news, I guess. I was kind of hoping for some kind of code that pointed to a bad sensor on the tranny. I guess the transmission need to be rebuilt.
A quote from the web site of Baumann Electronic Controls - "The bell housing pattern is different for a 4.6L or 5.0L/3.8L/4.2L engine and the two are incompatible. The two case types can be distinguished by looking at the starter flange area. If the starter has three attaching bolts, the case fits only 4.6L engines. A two-bolt starter indicates a 5.0L/3.8L/4.2L compatible case (casting number may begin with "F4ZP", not available before 1994)."
This quote leads me to believe that 5.0/3.8/4.2 all are bell housing compatible.
Put a add out that said I was looking for a AODE for a 94 Mustang w/3.8 V6. A guy called me and said he has an AODE that came out of a 94 Mustang with a 5.0. Anyone know if this will just swap right in with no issues? I am not sure, but I would say no. I think that the bolt pattern for a 5.0 and 3.8 are the same, but here is why I say I don't think it will work. I did some research and the 94 Mustangs with a 3.8 V-6 (AODE and manual tranny) use the EEC-V system (OBD-II). 94 Mustangs with the 5.0 (AODE and manual) use the EEC-IV system (OBD-I). I think this would make them impossible to swap out easily. Anyone know for sure? Any ideas. Thanks for your patience.
