Looking to find out what kind of 5 speed trans i have in my 93 chevy 1500 with a 4.3 engine

should be by the crankshaft pulley front bottom of engine

I Have a couple of questions. First question does engine surge when idleing cold? 2. Does engine start quickly without a lot of cranking, Cold or warm? 3. Do you have funny smell at highway speed, or after you stop? With out this info and your imput, I would only be guessing. I am retired mechanic of 25 years. and would like to help if u need me.

If you have adifferent plug for the speed sensor then you probaly have the wrong year model transmission.Even though 93 through 97 look similar they do not interchange.Your speed sensor should be on the passenger side of tail housing,That is the 1995 up design.If you have a trans with the speed sensor on the drivers side of tail housing then you have a 93 to 94 design.93 and 94 were non-pwm units with 5 solenoids.95 was a pwm unit with 6 solenoids with low impediance pwm solenoid.96 and up are pwm units with 6 solenoids and high impediance pwm solenoid.Swapping these units can blow computers.It is probaly stuck in third gear because the fuse is blown or because of open vss circuit.You will not be able to make this transmission work.

the throw out bearing is bad ,so change bearing and clutch

Not without a little adapting. The 1993 has a 4l60e which is electronically controlled and has shift solenoids. If the 83 is an overdrive it is a 700r4 which is the same trans but not electronic. If you put it in the speedo wont work and you will need to install a T.V. cable so the transmission will shift. The 93 won't go forward or backwards?

with the shifting lever there are bushings, you just need to replace them.

what color is the inside of the trans connector on the trans itself? I believe the 93/94s were a tan yellowish color. 1995 and up are different and won't work - electronics are different

If they have exactly the same amount of solenoids, you could switch the harnesses.... but it sounds like you have a 95 or newer trans which would have one more solenoid

Imput shaft bearing. It just happened to me. You're looking at a $400 fix.

The flywheel is balanced different. Use the 79 flywheel. The exhaust is all going to have to be changed. The trans., bellhousing will work.

Yes it will run, if it is identical as you told us, and you will have no problem with the safety switch, your only concern now should be the gear ratio of the 93 chevy Blazer.
