1951 Mack LJ Posted February 4 Share Posted February 4 I bought a truck and it came with a T2090 that was pulled from truck because it broke. Not sure what is wrong with it. Is there any value in these as parts or should I just haul it in for scrap?

mowerman Posted February 4 Share Posted February 4 Well, I don’t like to throw anything out and I don’t know anything about that thing. I’m sure somebody else will chime in….

Lmackattack Posted February 4 Share Posted February 4 I know they suffered from the ho low range syncronizer. they often grinded between range changes. Not macks best transmission but when they were working right they were not all that bad for a road truck. as far as value. they are not a popular option by people looking to swap in a diffrent transmission.

Vladislav Posted February 4 Share Posted February 4 The most probably the synchro clutch got worn out. It gets bad together with Hi mating gear. In this case you can't go in Hi but can in Low. Other common issue is worn sliding clutches which shift gears in the main box. Their teeth are square at the ends when they're new and get round when worn. You're difficult to catch the moment to shift with that. The condition of sliding clutches can be observed if you remove the main box top cover which is very easy deal. The synchro issue in the compound box needs taking apart to investigate if the memory serves well. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/75121-sell-or-scrap-t2090/#findComment-568611 Share on other sites More sharing options...

Joey Mack Posted February 4 Share Posted February 4 The good thing is the tranny on the ground. The 4th/5th sliding may be worn like Vlad said, it can be replaced easily through the front without taking the tranny apart, and stand it ,,, yoke facing up,,,,, and the synchro job can be done in short time.. no special tools needed for these repairs, just good snap ring plyers. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75121-sell-or-scrap-t2090/#findComment-568613 Share on other sites More sharing options...
1951 Mack LJ Posted February 6 Author Share Posted February 6 I have no interest in fixing it. Just don't want to scrap it if there was someone out there needing it for parts. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75121-sell-or-scrap-t2090/#findComment-568702 Share on other sites More sharing options...
The Heinz Posted February 6 Share Posted February 6 Could contact someone like Weller to see if they'd be interested in buying it. They have a pretty decent market for reman transmissions, maybe they'd be interested. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75121-sell-or-scrap-t2090/#findComment-568712 Share on other sites More sharing options...
