It made quite a bit of difference on the 310 tune, the shifting was smother and easier. Ive got the stock TCM in now since I had it at the dealer for work. I loaded up the updated tunes last night, the 310 is pretty smooth and a little softer since the update. I will probally leave the stock one in.drservo, how do you like your TCM? Make any difference?
IF you are not happy with the 275, don't try the 310. The higher the tune, the harder the shifts for the most part.I run 210 at the moment and i tried 275 once but shifting was so horrible that i immediately switched back. I was literally terrified that my tranny would call quits on me in a middle of an intersection somewhere. Now i got a bug up my ass about trying the 310 tune. How is the shifting on that for DD purposes? I got a stock trans at the moment.
Why not just try all of them? If you don't like it, try another.Crap...How long does it take for tranny to relearn? I was hoping to use a higher tune to travel from FL to PA next month, i been reading up that 310 yields better MPGs than 210. Hopefully i wasn't fed pork pies and a bag of trout.
In order to keep your factory transmission clutches alive, line pressure must be increased so that they engage and disengage in a positive manner rather than slipping through the shifts. The bigger tunes (250 and up) require the increased line pressure so that slippage does not occur. Slippage results in burnt clutches, which you don't want because you will be building your stock transmission quick This is why you see so many guys 100,000+ on stock transmissions running big tunes.Sorry for sounding like a rookie that i am but...Rough shifting is somewhat of a good thing?
