Late Model 5-Speed
[font size="1" color="#FF0000"]LAST EDITED ON 28-Jul-01 AT 08:46 AM (EST)[/font][p]I've got a 67' F100. I was thinking of putting a late model 5-speed with overdrive in it. It's out of an 88' and has a hydraulic clutch. Anyone ever tried it?

Advance adapters makes a kit for most of these, it allows you to install a ZF 5 speed. The problem is the price of the ZF is too high.
Depending on the engine you have, you might be able to install it with no real problems.
I've given up on finding a good price on the ZF and started looking at what someone else did. Put a Clark 5speed in. I've heard you can get one for a few hundred dollars and that it'll go in without a hassle.
With the cost of the tranny and the adapter kit, it's tough to justify the savings. If your really looking for lower freeway rpm, a gear change is the cheapest way to go, but you loose a bit on the bottom end.
If the truck is a street truck and light weight, you can try for a T5 or TKO tranny (car tranny) for much cheaper, the 5 speed truck trannies are usually big bucks and the car trannies don't have the granny 1st for towing / crawling.

I'm getting ready to put an 85' 5.0 out of a Stang in the truck. I pulled my Cleveland out to go into a MACH 1. I have a smallblock C6...but with 4.11s with a locker in the rear she winds pretty tight on the highway! I've got the T5 out of the Stang, but was worried about it holding up in my truck. Mostly it'll be a daily driver and to haul dirtbikes in the back. My neighbor has the five speed that was behind a 300 six banger. I'm told the bell housing is the same as a smallblock..but I haven't verified that yet. I could get it for cheap! I might tow a car trailer that weighs about 5000 lbs. with the car on it when the MACH 1 is finished. Can the T5 hang? Thanks!

I've been warned that that T5 from the Mustang is too delicate to deal w/ a much heavier truck. The Bellhousing for that T5 should bolt up to a 302 but the Bellhousing I believe has a different tranny pattern between older Manuals and the T5's I think you need to use the Bellhousing from the Mustang along w/ the tranny if you do that. I also believe the Mustang has a cable actuated clutch so you'd have to engineer that to work. I've seen some pple retrofitting hydraulic clutches too. The 5sps in light duty F150's from the 90s have a Tranny made be Mazda that apparently is also fragile. Tremec makes beefed up 5sps like the 3550 and the TKO that are made to handle alot more Torque.
