How reliable would a t56 be if I stuck it in my quad with the twins. I'm tired of the tranny issues with the 48re. I know some of the members have already done the conversion in their quads but I don't think any are f.i. Should I consider the t56 or a different auto tranny that won't give the problem I've had with the 48re. I just had this dam thing rebuilt 1500 miles ago at suncoast and the twins were on the truck only half those miles. The other day I was driving home and went to pass someone on the expressway, the truck down shifted like it was suppose to from o.d to third but wouldn't up shift back into o.d unless I let off the throttle. Then as i was coming down my street normal acceleration, the truck all of a sudden revved as if it were in neutral. Coasted to my driveway and put the truck into park, then reverse , neutral, drive, 2nd, and finally 1st. It wouldn't engage in any position. After a few minutes of continuing to do it it finally engaged but now won't highlight low 1 when I shift it to there. My tranny temps are good, no overheating issues at all. I let it cool down and decided to try it again. Started down the block and as soon as it went to shift it revved like if it went into neutral again and then once again could get it to grab any mode until after I kept shifting between them for a few. Fluid doesn't smell burned but looks a little dirty. Not bad though.
