Hello everyone. I'm looking for information on a Transmission swap. I have a 72 Grabber V8 Auto Floor Shift. I want to install a AOD. Here's my Questions. 1. What AOD transmission to use. 2. Who make's the trans mount. 3. What transmission cable do I use. I have a holley 600 CFM 4 Barrel on the engine now. 4. What cable mounting bracket on the engine do I use. 5. What "U" joint do I use with my Drive Shift. If I missed anything I would appreciate it. Thanks, John Cell # 352-584-9120
hi John, i used an '84 AOD i sell the mounts...AOD crossmembers in stock... www.Lokar.com has all the brackets and cables... driveshaft you have will work...may need shortened... same u-joints... you may want to put a 3:55 rear gear... ...frank...
Frank, Thanks for the call, It was good speaking to you. I appreciate the information. Now I have a reason to do the convertion. I'm going to the yards this week end and get my Transmission and all the related stuff. Will post my task as it happens. I have 2 third members to pick from. 325 to 1 or 390 to 1 both 9" posi's. Regards, John
Depending on your engine build-up, a 3.90 (probably a 3.89) with an AOD would be quick and fast, as well as good on the highway. Frank did this conversion right. I would definitely pay attention to him. (Now I gotta go say something bad about him in another thread just to keep his normal sized)
Terry, It's a 390 to 1 . It came out of a 68 F100 240 6 Cylinder Standard Transmission. 28 splines. John
I've got a 3.89:1 gear set. Ford must've rounded up on their ID tags or that was fluke gear for that year. Richmond Gear doesn't show a 3.90 gear for the 7.5, the 8, the 8.8, the 9, or the 9.5 rear ends. However, if I could tell difference in the performance of 3.89 gear and 3.90 gear, I would really be one gifted and talented individual. Assuming 26.5" tall tire, 100 MPH with a 3.89 gear would have you running 4,932 RPM. With a 3.90, it would 4,945 RPM. Can you say, "big deal?" By the way, welcome to the forum.:Handshake
Terry, My miss take. It's a 370 to 1. Not a 390 to 1. I'm planning on finding a wide ratio AOD. One out of a late 90's model F series pick up. Once in OD with 370's it will work out to be 250 to 1. That should give the range I'm looking for with a 15 gallon gas tank. Thanks again, John
Thanks. I thought this 49-year old brain was malfunctioning. 3.70 gears and AOD will be nice. However, our F250 has 3.70 limited and automatic overdrive with a 7.5 EFI. It gets 11 MPG. Period. It gets that empty, loaded, trailer, no trailer. If you get one out of a late '90's model, won't you need some kind of computer controller? I know in cars they ADOE's and you need a computer. Baumann Engineering, makes a stand-alone device for just the transmission.
Wouldn't that be an AODE? If so, that's a whole different ball of wax. Edit: Sorry, I didn't see Hawko's reply. I walked away from the page and didn't refresh it before posting.
It is entirely possible that the trucks have E4OD's. Those are a smidge bigger than the C-6 and you fitment problems in a Maverick.
Ok you got me again. I've should of said, early 90's. F150's. In a Vehicle that weighs APX 2700 lb's. Like our Mavericks / Comets with 370's whould give you the benefits of a lower ratio ( 389 to 1 ) Plus in OD have the high-Way gear ( 250 to 1 ) for the long runs.
I'm most of the way through with my conversion. How do you adjust the Lokar downshift cable? Do I need to order this gauge the instructions suggest? thanks Phil
that is the...up shift... cable. the way i adjusted mine was...i took all the slack out of it... that way it starts building pressure from the start. this needs to be right before you drive the car. ......
