Denny Posted February 14, 2010 Share Posted February 14, 2010 What is the difference between the T200 series and the T300 series transmissions. I have a T2090 in my R model. Are they any more driver friendly, or easier to shift? I've been thinking about swapping out the Super10 in my CH for a T310. But are they really better than the 200 series? I really like 2090 In the R, but I have to clutch to come out of gear in the high side to make a really smooth shift. I also need to look at the ratios to see if they are pretty close to each other.Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/12650-t300-series-trans/ Share on other sites More sharing options...
Mackpro Posted February 16, 2010 Share Posted February 16, 2010 This is from Mack. I tried to copy and paste the service bulletin but the chart didn't come out right. The finer sliding clutch teeth makes it shift better than the T-200 series but still not as smooth and a half worn out Fuller.

Denny Posted February 17, 2010 Author Share Posted February 17, 2010 Thanks for posting that MackPro, just reading through it tells me that Mack has not improved that much over the 200 series. I was hoping that they upgraded enough to be with the times. Sounds like as much of a pain my Super 10 is, I better just put up with it . Thanks Again Quote Link to comment https://www.bigmacktrucks.com/topic/12650-t300-series-trans/#findComment-49858 Share on other sites More sharing options...
maxidyne237 Posted February 17, 2010 Share Posted February 17, 2010 How have these transmissions been holding up over all? The range syncronizer better than in the 200 series?

Mackpro Posted February 17, 2010 Share Posted February 17, 2010 How have these transmissions been holding up over all? The range syncronizer better than in the 200 series?The syncro's are better but we still change alot of them. The main problem is the driver/trainning, then Mack had alot of problems with the range shift fork bolt backing out and also the out put/rear yoke bolt getting loose and causing syncro failures. I would say 90% of the time it's not the syncro's fault.

Denny Posted February 18, 2010 Author Share Posted February 18, 2010 Mackpro, Why does the range syncros still fail, is it a lack of preselecting the range button? Then grinding the syncros?
