Would a 94 Astro van 4.3 transmission fit 2003 Chevy Silverado 4.3
No, 2 totally different systems, they might bolt up but there will be no way to make the 94 work with 2003 computer controls.
Thanks what other model transmission fit on 2003 chevy silverado 4.3
Look on the drivers side of the trans, there should be a tag on the case that has a bunch of numbers on it plus the type of trans you have, those numbers need to match, it could be out of a Chevrolet or a GMC, they just need to match, try a wrecking yard for a warrantied used transmission, if your trying to save yourself some bucks and can do the job yourself, that way your only out the time putting it in if it doesn't work and the yard will give you another one to replace it, the last used tranny I put in a car for a guy worked just fine, he picked it up and brought it too me, so as always I popped off the pan to look inside and too change the filter and it looked brand new inside, put it back togethe, put it the car, added some LubeGuard and filled it up and off he went happy as could be, saw the car a year later and he was still driving it and had no more tranny troubles. Just some experience with used trannies. HTH
My transmission was working just fine and I was going on the freeway and need just one down to 3rd gear and it didn't change from there and when I pull over it wouldn't you know it wouldn't run because he wasn't there again you think it's the transmission or you think it's something else
Early generation electronic transmission, could just be a stuck solenoid, quite common, a tranny shop should be able to plug in and test it, but you have to get it there.
