Sorry there is no cheap way out the syncros are prone to failure. The problem is useally in the back half of the trans. It is hard to find original parts for the back Mack offers updated syncros and gear hubs that help the problem with the original design You cant mix the new updated mack parts with some of the original parts so you have to buy every thing. Its around $1500.00 I had the back of my trans rebuilt and its ok It still makes a little noise during range shifts. Mack has an alternative shift pattern low 1 2 3 shift range then shift like a 5 speed mack on the high side You dont use the highest gear on the low side but you use the lowest on the high side I know this is hard to understand. Remember I am a driver not a writer. (note: this does not work with T2090B transmissions ) I shift mine like that and it seems to work good it is kind of weird at first but you will get use to it you can get a Remack factory rebuilt unit but they are around $4000.00 It kind of sucks but what are you gonna do?

I have a 89 R model with a 300 and a T2060. The truck needs motor work. The clutch is also bad so an in frame overhaul wont help my situation. I am going to pull the engine but I need someone to rebuild it. I am looking for a Mack engine rebuilder in the Chicagoland area. I rather not work with the mack dealers. I would appreciate any references. I think word of mouth is the best way to do business. If you have a good motor guy please let me know
