KyIH Posted November 25, 2022 Share Posted November 25, 2022 I am looking to buy a reman mt643 and was wondering if anyone here had any recommendations. Are some remans better than others? Weller, Transaxle, Valley Truck, RTS Quote Link to comment Share on other sites More sharing options...
Paystar5000 Posted November 26, 2022 Share Posted November 26, 2022 We have used 8 valley truck and 1 or 2 from weller. Have had no problems with either. We have not used a transaxle one in probably 15 plus years. Our kenworth dealer sold the valley ones. The parts guy there was very good which was probably the reason why we bought so many from them.

tractorholic Posted November 26, 2022 Share Posted November 26, 2022 (edited) What are you putting it in? I thought a 653 is a better transmission because of the low gear it has. I don’t remember who done the reman on that transmission so I guess I really can’t answer your question.

KyIH Posted November 26, 2022 Author Share Posted November 26, 2022 It’s going in a IH 4700 box truck. Low gear shouldn’t be an issue. I bought it with a bad at545 and converted it to a 643. I bought a used 643 that didn’t last long at all. This time around I’m going with a reman and replace the radiator/trans cooler. Thanks paystar for the info. I was leaning towards valley.

Lars (midessa) Posted November 26, 2022 Share Posted November 26, 2022 Does Jasper deal with those transmissions? Quote Link to comment Share on other sites More sharing options...

The last few pickup transmissions we have put in require radiator/ cooler (Chevy) replacement to get the warranty. If it had big time catastrophic failure replace the hoses.
