Re: How much adjustment can be made?
That band adjustment may not be a cure all. The kick down linkage also can affect shift points. Low fluid can hurt. Maybe change your fluid and filter first. Of course, band adjustment is not a routine procedure, you adjust it because something has changed internally, this is usually not a good thing. Back to your first question about rebuilding, you probably are going here eventually. Get a good rebuild manual for your transmission, (check out ATG). They are not cheap, but you don't get this kind of info out of a Chilton's or Haynes manual. You probably will get a "master rebuild kit" which includes all soft parts like seals and gaskets. You may need hard parts like planetary gears if they are broken. They are sold seperately and usually are not cheap. Maybe find a donor tranny for parts. 2WD ones work fine and are usually cheaper than 4X4 tranny's. The only difference is the output shaft and rear extension housing. I think the truck C6 may have had different gear ratios than the car C6, so do some research. You may need some special tools, but you can usually fabricate or adapt existing tools in most cases. As far as skills go, if you can stack parts in the right order and make a few precision measurements, you are a fully qualified tranny mechanic. At least you are as qualified as the trained ape who will probably put your tranny together at Joe's tranny shop and Deli. I have not had good experiences with tranny shops and while there must be some good ones out there, I don't seem to find them. You may find the tranny parts business seems to be a closed shop. You're probably right, but the counter guy can usually be talked into it. Just don't expect a liberal return policy and pay cash. One final suggestion. keep everything clean! This means buying lint free shop towels instead of ripping up old rags. Good luck
