02 Impala trans info needed

Trying to help a friend locate a used trans for his 2002 Impala with the 3.4L. I know it's a 4T65-E, but need to verify what gears are in it (if different from a GP GT). If not the 2.93's then how can I tell what ratio it currently has in it?
 


should be a tag on the trans somewhere with a code. get that code and call the dealer and they will tell you, or grab the VIN and call the dealer. Service dept will be able to tell you by the vin.
 
Tag is one, you could pull the sungear and count teeth.

Although a sure way to know you are good is to swap the diff/sungear over and then you can use any NA trans.
 
Thanks guys. I'll have them look for the tag and go that route. Car is at a shop somewhere and they're trying to wring 3k out of him for a rebuild.
 
I look on car-part for any 4T65 in an NA car 98-02 for that, then swap the diff if needed after counting teeth. I don't even look at gear ratio when buying. Just go on mileage and price. Then deal with ratio at the diff.

When flipping Imp's over the last year I have nabbed many $100 right about 100K transmissions.
 
I'm gonna check car-part and craigslist around here and see what comes up. Can't see paying more than $3-400 for one if low miles.
