I picked up the kit from ebay and it was this one specifically. They answered the phone when I called during regular business hours and were very helpful. Oh, and make sure you have an inch pound torque wrench. So the PSA is, follow the directions and follow them exactly. There you went and spent $150 and because you couldn't follow directions you are now spending an easy $1000 or more for a new transmission. if you misplace a little ball, drill a hole too big (or not big enough), miss changing out a spring, or put a bolt in the wrong place you stand a serious risk of destroying your transmission. You're probably going to read over them say 5 or 6 times. The biggest benefits in my mind are that the transmission should last longer since there's less slip on the clutches.įirst things first, you're going to look at the shift kit instructions. I've noticed the downshifts are quicker and a bit harder, but I see this as a huge benefit since the transmission would mostly refuse to downshift when I gave it gas to pass other cars.

It's a big heavy, 4x4 with a heavy slant towards offroading. WOT shifts are hard and sudden and very high in the rpm band, but I rarely floor it and I don't see the behavior in this situation to be relevant. Partial throttle shifts are largely the same as stock and during general driving around the shifts are just a bit harder. I can't say there's any downsides after doing it. I recently installed a shift kit while changing the filter and fluid at 100k.
