Thread: E4OD in 73 Mach 1

Tweet

Ya' know, it popped into my head overnight that my 2017 F150 with the "Max Tow" package can handle a 12,500# load, but it has three options on the shifter for the 10 speed transmission - OD, Tow/Haul, and Sport. The Owner's Manual is clear that when pulling a trailer, or with a heavy load in the bed you're to use "Tow/Haul" to prevent damage. It keeps the tranny in lower gears, and the RPM's in a tighter range for Max Torque, all electronic. OD shifts out to keep RPM's low, and Sport keeps the RPM's above about 2000 so the turbo's are spooled up a bit, ready to kick in boost.

I'm thinking that your idea of running through your dynamometer climbs with a load is going to require more than just popping the tranny into OD and forgetting it when pulling a trailer. Again, I'm no tranny guy so I would be talking to some "experts" about how to get the most bulletproof package. Maybe there's someone here that hasn't chimed in yet but has some answers.

My introduction to modern trans started in 1994 when I got an 84 E350. It came with a 460/C6. I swapped the C6 for an E4OD, and the 3.06 rear for a 3.5 dually. I swapped the trans to get a locking converter. It uses a first gen Baumman controller which has two profiles. The only difference I have programed is one profile locks the converter in third and forth, and the second profile locks only in forth. So I climb hills in third/locked, and everything else is forth only lock.

I have an AODE behind a 427W in a 65 Mustang. That has the current Baumman controller. It has four profiles. When memory got to be cheap it allowed the software engineers to go crazy, which made for a serious learning curve for the user. The number of "buttons" can be overwhelming.

I have built two E4ODs. One has been in the 84 Van for about a decade, is a daily driver, and has been all over the country, has done three Hot Rod Powers, and is doing this years. And it tows.

The second E4OD is waiting to go behind a 532 in my 63 F100.

I have the parts to build another for my 73 Mach 1.

The AODE and all E4OD get triple disk converters. I once had a single disk try to lock in third under load, strip all the friction material, and we went home on a flat bed.
