The next mods are going to be a good cooler and an inline filter. I dropped the pan, changed the filter, added a B&M drain plug in the pan, put it all back together then did a cooling line flush to make sure I got all the old DEX III out.įor about $100 for everything I am very satisfied with the end results and I am sure it will help the life of the transmission. I would have liked to have done one at a time but I only had a few hours to change servo and fluid so I did them both.Įverything about Dexron VI is far superior to Dexron III. I cant say for sure if it is either the fluid or the servo that had the biggest improvement or a combination of both. All others I looked at was synthetic blend.Įnd result is it woke this transmission right up and shifts are instantaneously, holds gears much better going up hills it use to kinda hunt between 3rd and OD. At the same time I also flushed all the fluid out and upgraded to Valvoline Synthetic Dexron VI, as far as I know Valvoline is the only 100% synthetic Dex VI, I could be wrong like I said as far as I know.

Other special tools/advice I'll need? pump pulling tool? ATSG manual in the mail.I upgraded to a Vette servo in my wifes 2000 Bravada because the shifts was so soft it was hard to tell what gear you was in. This servo is a must for any performance, towing, RV, or off-road transmission, but would be a nice upgrade for any 700-R4 or 4L60E. Anyone have a link to the bit to take the bellhousing bolts out? I hear its a special torx?ģ. New USA made Corvette servo piston kit for the GM 700R4, 4L60, 4L60E, 4L65E, 4L70E, 4L75E THM700-R4 MD8. Do I need a special tool to get the cooler lines off?Ģ. So now the plan (provided theres not a bunch of aluminum or spring bits in my transmission) is to swap all of the internals to a new case.ġ. I have no idea what happened, everything seemed to go in without much trouble, I did have to put a good amount of force on the cover to get the snap ring to seat, but seemed normal from everone elses posts. The servo cover snap ring was cocked halfway out and letting the cover leak. The Torx bit you will need is the T50IP Torx, not the same as the T50. Pop the wire clips out and the lines will pull right out.

If not, you can get away with just using a pick tool after you pop off the little plastic clip lock. Its a small chip from one of the little access notches on the servo boss diagonally outward. You dont need a special tool for the lines if you already have a fuel line tool. So I installed the Corvette servo in my 2007 Classic 2wd 1500 and it felt great for 2 days.then my truck doesnt want to shift to second and is dumping fluid out on the highway.
