Hello my name is Christina I own a 2004 Monte Carlo I am having transmission issues I have the 3400 sfi and I got someone who owns a 2000 Monte Carlo with the 3.4 in it will the transmission interchange?

 

Hi Christina, and welcome to the forum.
The transmission must be an identical replacement. Even though both have the 4T65E transmission, there are differences. There is a tag facing toward the rear of the car on the passenger side of the transmission with some numbers and 3 letters that run vertically. (Really hard to see without a mirror or phone camera). Those letters will be like "LBD". They need to match.

 

Ty so much !! I'm new to all this and I am kinda broke after buying this car I've put so much money into it SMH now this ugh I don't know what to do

 

Really sorry to hear that.

Hi Christina, sorry to read about your problems...So many people have them today...We just have to keep on fighting to stay on the road.

If you can/t find the #, I suggest calling a local transmission shop and asking them your posted question.

Like Bob said there are many internal & electrical changes between years on the same model transmission.
Yours and your friends are both 4T65E
