hi ,ihave a 94 SC ,that has a slippping tranny,does anyone know what is the most durable master repair kit avail? thanx..

Sonnax will provide the updates. It'* pretty much the standard rebuild kit for 4T60E'*. If you are interested (and I highly reccommend it for performance and long life) a shift kit, get the TransGo 4T60Ejr. An adjustable modulator would also be a very wise investment.

thanx for replying,what does a adj moduelator help??

It replaces your tired old vacuum modulator with a new fresh unit, that you can use to increase your line pressure and firm up your shifts. The TransGo shift kit is the best alternative, but even by itself, the modulator can gain you some of those advantages. The shift kit AND the adjustable modulator are an unbeatable combination. I have both on both of my cars.

what do you mean by "sonnnax will provide updates??
do you know where i can order a street/strip master repar kit?????
thanx

Sonnax is the brand name of the kit manufacturer.

thanxfor the info,is there a specific model they offer that you have heard good this about for durability???i plan on going to the track with this car a couple times a year??
