I converted mine last winter. The stock auto finally got to where it wouldn’t go into reverse. Mine was no big deal on the electronics since it was the 47RH. The PCM works fine with the 5-speed as well as the cruise control.
I found a fellow in Missouri through an ad in the classifieds that had a 1994 2WD 5-speed that had been totaled in a rollover. He sold me practically everything I needed for $1500. That included the transmission, flywheel, stock clutch, bell housing, clutch hydraulic system, pedals, shifter, front half of the drive shaft (the yoke is different), transmission mount, and all the bolts and hardware.
The stock clutch had been dropped on the edge and had a couple of small chips out of it and I want to do some bombing so I bought as SBC Con-O for $650. I had the flywheel ground for $25. I also went with the new roller pilot bearing which required flywheel modification that a friend did for free.
I installed the pedals, which was no small job. I paid a friend who owns a transmission shop to do the swap $280. He removed the auto, all the lines, and the cooler. I had to remove the seats and the carpet. The only modifications he had to make were to cut the hole in the floor for the shifter and rewire all the switches. He installed a new rear main seal for me, also. I think the seal cost me @ $35 at Cummins. We also removed the bulb from the transmission temp warning light because we couldn’t get it to go off. The cross member had to be removed and turned around backwards and the front half of the drive shaft had to be lengthened ¾”. The drive shaft work, including replacing a u-joint, cost me $125.
I sold the old transmission, cooler, and lines to a fellow for a 1st Gen conversion for $250 and I sold the stock clutch on eBay for $50. So, all in all, it cost me $2315. I did a lot myself and had friends do the rest, so if you have to pay someone to do it all it may not be cost effective.
I love it. Solid drive, no more slush box, I can do some bombing without worries, and I picked up 3. 5 MPG with the conversion. I’d do it again in a minute.
