Re: Important Transmission Question
Err, no. Ford never used "AOD" transmissions behind 4.9 straight six trucks. They used the 3 speed C6 transmissions up until they introduced the "E4OD" transmission. I believe the reasoning was that a 4.9 put out more torque than an AOD could handle in the long run.
I believe it could be done though. An AOD from a 5.0/5.8 vehicle will bolt right up to a 4.9. You'd need an odd flexplate though. The 4.9 uses no balance weight where the V8's use either a 28 or 50 ounce weight. Perhaps you could grind a weight off? Ford never made a "TV" cable to fit a 4.9 so you'd have to get one of the Lokar cables and adapt it. The "TV" or "throttle valve" cable is all-important to the AOD. Adjustment is very sensitive and a large misadjustment will kill the AOD. The shift linkage will be wrong, some from a 5.0 AOD truck of similar year should work though. If he is pulling out a C6, the driveshaft front yoke spline will be incorrect, as will the driveshaft length.
Most folks wouldn't want go to all that trouble.
