I agree with Jackie- I have a Super 10 on my WhiteGMC/Volvo W1A64, and if you take care of it, it'll take care of you. Consider replacing the shift solenoid, and having the Top 2 "feature" turned off in the ECM, and it will last a long time- just about as long as any other Super 10. I currently have 1,025,659 original miles on my Super 10 and it has only needed a shift fork (due to the severe duty driving I work in every day and the previous drivers of my truck floating gears). It can be replaced with a Super 10, but that will be expensive compared to replacing the Shift Solenoid and turning Top2 off. Hope this helps!
