Can I use this trans?

[94GrandPrix]

So I need to replace the transmission in my GP. It's a '94 SE 3100 v6 w/ the 4t60e. I'm assuming i can use any 4t60e from any W body from '94-'95 as long as it is equipped with the 3100 v6. I could be wrong about that though?

 

What are some things I should look for in a junkyard transmission, other than low(ish) miles. I was going to drop the pan in any trans I deem may be suitable for my car to look for excessive clutch material or any abnormalities (burnt fluid, chunks of metal, etc). I was also going to replace all shift solenoids for added insurance.

 

Thanks in advance guys!

I've beat this topic a couple times so let me sum it up for you.... 91-93 trans are slightly different, I believe the PWM is on the outside and not the inside, and I also think they don't interchange with the 3100s. 3100s are similar from 94-97, just verify the trans is the same. You want one that has the Vacuum modulator (big issue) and the round connector to the trans. Take a pic of your current trans and go from there.

 

Also, look on car-part.com . I found a low mileage trans for my Cutty out of a 95 Monte Carlo. Works perfect. Just had to travel up to PA but worth it.

Almost certain a 91-93 will have issues with TCC lockup, something about the way the ECM commands the TCC. If you have the option, I would use a 94-95 like you said shouldn't have any issues, except from a 94 lumina, I think those were still the old style as I know they didn't get the 3100.

 

Picking out trans suck imo. I bought a supposedly good tranny from a friend once. Looked good, fluid clean, low miles. Put it in, no 4th gear

Finding a used trans from any 94-95 w body isn't going to be a problem here, as a used trans for a u pull it is about $100 ($75 plus a core charge) and there are several of them.

 

I planned on checking it thoroughly and replacing the shift solenoids, lock up solenoid, etc.

 

Thanks for the feedback guys! Just wanted to be sure about properly matching up the trans.

You should try for a 97, from a Cutlass or Monte Carlo.

Try to use the broadcast code on the plate attached to the casing to identify which gear ratio your trans has (more than likely it could be the 4CMW), differential & sprocket ratio plays a part as to which torque converter is in front of the trans,
