Chevy Silverado Transmission
« on: September 09, 2011, 02:53:15 PM »
I need a transmission for an '88 Silverado 1500 2WD regular cab, regular bed, 305 5.0. Automatic. Does anyone know what transmission they take?

Does it have the 3 speed or 4 speed?

Three speed is a TH350, 4 speed is a 700r4. Both have the same bolt pattern, so if you have the 3 speed but want overdrive.. get the 700r4. Just make sure they came out of a truck so they have the long tail shaft.

Thanks! I believe it's a 3......I have only driven it a couple of times, but bought it for $150 from my stepdad. 356k on the clock....needs a tranny, and it started smoking under the hood last time I drove it.....

Throttle body fuel injection?  If so you are probably looking at a 700R4.  Th350 should bolt in place though IIRC.  Make sure the replacement trans comes out of a 2WD truck, as the 4x4 trans has a shorter length (transfer case attaches directly to rear of trans).

carb'd. It's a 3 speed. i think i'll take ling's advice and get a 700r4. I would like to make it a teensy bit more efficient.

It's the better choice, it will have better get up and go in first gear, and will have better fuel mileage. Everything should bolt right up, not sure but the speedo gear could be different so you might study up on that.

I'm pretty sure it's more involved than that... crossmember relocation, TV cable (proper adjustment is key), TCC lockup wiring, etc.

Wouldn't make sense to have to re-locate the cross member.. that would mean production would have to be different for essentially the same thing. I could be entirely wrong about that, but it just doesn't seem like it would make sense. And it would also probably mean a different drive shaft length.

When I switched from the 700r4 to the World Class T-5 there was no re-location of the cross member, although this is in a Camaro but still.

ling, you're talking about Chevy here. They're fucking retarded when they design shit. Could use a different crossmember. Mounting points are on the frame, so no way that is different (different frame for same truck??? no way).
...and either quite drinking or quite posting because you're going into some sort of weird AMERICA 1776 FUCK YEAH mode.

It is a different crossmember. Just drill some new holes and use the old one.
