4 to 5
I have a 1986 F-150 short wide. XLT Lariat, dual tanks, 2 wheel drive, 302 FI, etc. Pretty nice truck. It has a 4 speed transmission with granny gear, nine inch with posi and 3.50 gears, and 235/70/15's. I run this truck on the interstate at 75mph a lot. The motor turns well over 3,000 rpm, often for four hours plus at a time. Recently I pulled a T5 out of a 5.0 Mustang. It sure would be nice to have overdrive. What would it take to put a T5 in place of the 4 speed? Bellhousing, clutch, crossmember, speedo gear, driveshaft, and all that. What can I reuse as is, what do I need to modify, and what do I need to buy to make it all work? The truck has a hydraulic clutch in it. Didn't 5.0 Mustangs use a cable? The motor in this truck needs to last and right now I'm flogging it pretty hard. Done a few motor swaps, but never a tranny swap. Will I need to cut another hole in the floor for the shifter or will the stick come through the hole for the 4 speed? The carpet looks like it was recently put in. Any information, no matter how trivial it may seem, will be very much appreciated. In the future I may put 295/50/15's in the back and 225/50/15's in the front. A taller tire in the back will likely drop the rpm's down too. That's a ways down the road though. Just bought four new tires for it.
