automatic to 5 speed transmission

Have you looked for a 5 speed? My brother in law could not find one to replace the original 5 speed in his 93 GMC.

its a chevy....anything is possible, and theres tons of parts out there to do it.:laughing:

ive done it twice in early 90s cummins/dodges; not really hard to do, its just finding the parts to do it.

the easiest way is to find a complete truck w/the 5spd, so you have all the little parts you will need.

Difficult to impossible. Impossible if the crankshaft isn't set up for a throw out bearing.

Standard to auto is a snap. Back in the day the best shifter pricewise was from a Ford with a floor shifter like in a mustang.

But auto to standard is a whole nother animal. There's the clutch and all that goes with it. Plus the gears will be off, autos always have higher rear end ratios, and then like I said, if the crank doesn't have the place for the throw out bearing, you're looking at another crank or motor.

FYI: Cluth throw out bearing rides on the transmission bearing retainer. Crankshaft has nothing to do with it. Only thing pertaining to the crankshaft in a manual transmission is that it has a pilot bushing in the end to accept the input shaft of the transmission.

You're right of course. The end of the crank holds the pilot bushing. Sometimers working on alltimers more these days....

I changed a 1989 Silverado 4.3 5 speed over to a 5.7 auto and put everything back as it should be. At the time I bought a 5.7 roller motor and trans out of a wrecked police car for $400. and sold the 4.3 5 speed for $800.
BUT, this was all 2 WD.
All the 6 cyl and V-8 sensors were the same the only thing I had to change was the computer chip. I had to wire in the torque converter lock up from the trans to the computer. 5 speed had a shift light on the dash, it is the same circuit as the lock up. I did have to change the column and remove the clutch peddle.
I drove it 100,000 miles after that and sold it running great.
