5.4 trans for 4.6 swap
adrianspeeder did a thread on transmission types. I have a 98 5.4 trans that I want to use in a 97 4.6 truck. It looks like they are both E4OD type. Is it a direct swap and should I use the 4.6 torque converter or the 5.4? I found a cheap 97 truck that needs a trans. Do not want to get it if my trans will not work. Also the answer I get from you guy's, I will file in my truck book.

It's most likely a 4r100. some times they put 4r75w's behind the 5.4 in vans and expeditions. The 4r75w is a beefed up 4r70w found behind the 4.6. As far as I know the 4r70 and 75 will fit behind a 4.6. The driveline behind the 4r70 and 75 in longer than the one behind 4r100 and the tranny side flange is different.

The 4R100 has a turbine speed sensor and an output speed sensor. The computer needs those inputs. The E4OD doesn't have either one.
It didn't "go over tolerance." A tolerance is an allowable discrepancy in a specification. For example, if you specify a torque of 100 lb-ft +/- 10 lb-ft, the 10 lb-ft is the tolerance.
There is no tolerance on a transmission's torque rating. There is just an upper limit. The E4OD was replaced by the 4R100 in part to raise the torque rating. I forget what the E4OD was rated for, but the 4R100 is rated for 1000 lb-ft AFTER the torque converter multiplies the engine torque.

4.6 to 5.4 Engine Swap
I have a 2001 Ford F150 King Ranch Super Cab (4 door) with 2004 Lincoln Navigator 5.4 DOHC Intech 32V. The engine was installed in 2005 and was removed from a 2004 Lincoln with less than 100 miles on the odometer. The engine is backed up by a 4R100 transmission and 9.75 ring/pinion 3.73 ratio rear axle. The truck also has a true dual exhaust system with X pipe and number 50 mufflers. Great truck has been trouble free for over seven years. HP went from 210/220 to 300, torque from 290 to 355.
