Re: 4L60E Trans Shifts hard from 1st to 2nd?

Anyways, my truck's been shifting hard (1 to 2, hard; 2 to 3 okay; 3 to 4 just a little hard shift) and threw me an engine code (it's done it before, once, I'm guessing it's the same code for the tranny) and with 130k miles on it, I'm sure the tranny's trying to tell me she's gettin old and worn out. I pulled the dipstick to make sure, the tranny fluid smelled kinda funny, and there were chunks of material on the dipstick, assummingly pieces of my clutch packs.

So I'm figuring I'm going to have to have my transmission replaced (which would happen in a few years anyways, so might as well get it done now). So when I go down to the Clutch and Transmission shop, what should I ask them for? A stock tranny would work, but you guys were talking about these kits... now, this thing is my DD, and I'd like it to shift rather smooth, ya know. Don't want to be just cruisin the main drag, and at every intersection be snapping my neck, just at a normle take off (now, a full throttle take off is different, but that's a different story).

So my question is, while getting a reman'ed, or rebuilt tranny, what should I request for it? Anything special? Just ask for a rebuild? Ask if they can get me a rebuild and put some stuff in it?
Decide on how your drive your DD. Do you drive it like a normal working stiff, or do you want a little performance and sharpness in the shifts (designed to be there)? I have had a couple of trannys reworked through my local buddy and his shop and for them, we chose to upgrade the internals to heavier duty clutch packs and the valve bodies have been upgraded to the harder seperator plates (common problem with 700s and 4L60 trannys). On my DD truck (as well as my Sport truck) I spent what I could to get the heavier duty planetary, sprags and gears; along with the upgraded shift kit. I run my truck around 21,000 miles a year in daily use and want it to shift solid and quick. The improved shifting should help with the life of the clutch packs, less slippage on each and every shift controls the wear. A soft sloppy shift allows the clutches to slip and wear is created. I also added a "Corvette Governor" to assist in the shifting and m aking it where the truck would shift under acceleration, when needed.
