T5 or built C4?

. The car will just have an 89 gt motor with a cam and a few bolt-ons, and will only see about 50 miles of driving a week. It will mostly just be an around town toy,

This is your post so why do you want OD just curious. You asked about an OD or 5 speeder and now you are looking for or actually have an AOD-E electronic tranny you want to use. With limited highway use as you posted and 50 miles of driving a week. YOU HAVE ME CONFUSED and i do not know what you are trying to DO HONESTLY Thanks
Just curious what is your final drive GEAR RATIO??? I know you want the OD for highway trips as yo stated but i am still Confused as to your actual setup you plan on building???

Ah I am wrong. All of the aod/e/4r70w tailshafts are swappable, but the mark vii output shaft is the critical piece @ 1" longer. I can swap the tailshaft with my cougar's stock tail, but then my stock driveshaft slipyoke *might* bottom out on the mark vii output shaft when the suspension is fully compressed.

Seems like I'll be getting my driveshaft shortened after all...

Yeah the output shaft is the problem. For some reason Ford decided that the Mark VII and Town Car should have a longer output shaft. Why? I have no idea. I think it was just a way to make Lincoln different.

I had thought about putting a wide ratio gear set in my AOD when I had it rebuilt. The trans guy said not to bother as I would just incinerate the tires even easier. He was right. With a 3.73 gear and the 2800 stall converter I can absolutely destroy my tires on launch and the 1-2 shift. The wide ratio gear set would have made it worse. According to him he hasn't seen much of an improvement it E.Ts with the wide ratio gear sets behing 302s or 351Ws as they make a bunch of low end torque. The 4.6 and 5.4 mod motors benefit more from the wide ratio set as they don't have as much low speed torque production.

Each case is different though. A high revving small block (7000+ rpm) would probably need the wide ratio set up as it wouldn't make good low end torque.

This entire post was about durability vs. practicality. IF I would decide down the road to drive the car more, I wouldn't want to be intimadated by the low economy of a non-OD trans. That is where my desire for OD comes in.

The only mention I made of ANY electronic transmission (be it AODE or 4r70w), was the fact that the tailshafts are swappable between all AOD type cases.

My final drive ratio will be no lower than 3.73, and I'll just be running an HO motor with an E cam, headers, ported E7's, RR's, and a 650 carb.

I know you're more intelligent than myself Sir, but if you'd read each post more carefully, you might not be so confused. Thank you for your input.

Its not that i am more intelligent. When planning a build its always good to know what you want. I posted that the transmission can be had as a close or wide ratio. I would think you should know what your setup will be before jumping into a build. As thunder jet posted he was comfortable with a close ratio unit. If people get defensive when info is posted by others then WHY ASK. I find this on other sites as well. If someone answers a question and the poster that asked it in the first place does not like the answer they gets MAD. Then why BOTHER asking if you already have a PLAN. Some get mad when the answer is correct as well. I cant for the life of me figure that out?? Sorry for clouding the discussion with FACTS!!!! Thanks.

You're right Tom, I was out of line with my smart a** comment. I apologize. Just to clear things up, the transmission I have is a non-electronic AOD with a 1" longer tailshaft and output shaft. Thank you for helping me with my decision. If I had the money I would go with a built T5 or TKO, but for now a second-hand aod with a few mods will have to suffice.

No Worry's 87 that is what the talk sites are all about. Good luck on your build. I am sure it will be a good one. No need to apologize.
