Hey im new here and i got a 76 monte carlo that has a th350 tranny already in it and since its hopefully ganna be a daily driver i am just wondering what transmissions are out there that would help on mpgs? any advice is appriciated thanks.

 

Go smaller rear gear (3.73 and lower) or if your foot is not lead-foot, you can swap it to 200-4R. I'm not sure how your frame is, so you may need to drill new hole and slide the crossmember, or you may need to get TH-400 Crossmember.

But be careful. Stock 200-4R is not known for strength, and if your engine is 350 or bigger, it may not go well with the torque it makes. You can make it to survive, but it's gonna cost you. It may pay for it in a long run, but if you not planning on keeping the car, this could be an expensive option.
