?'s about shift kits
Re: ?'s about shift kits Traditionally these modified the hydraulics
to give more clutch clamping force, faster
applies, etc. Supposed to give better
performance and less wear, make it harder
to burn up clutches, etc.
I don't know how this all works with the
semi-electronic 4L60E (I say semi-electronic
because hydraulics still do all the work,
the electronics just say when and what,
and have some input to line pressure etc.).
But I've got one coming in the mail, so I'm
pretty interested in experiences with the
Trans-Go kit. Things like which setting you
used, whether it's too soft / too hard /
just right (for what kind of setup), things
the install instructions left out, and so on.
I don't like the shifts on my A/T, especially
when I'm letting it haul up to 50 but then
have to let off for traffic, that 2-3 upshift
just haannngggssss and sands those poor little
3-plates-short clutches. I'm hoping for more
decisive (and faster, I hate it when I mash
the pedal and have to wait a second or two
for the kickdown) out of the kit. We'll see....

Re: ?'s about shift kits JimmyBlue pretty much sums it up. I just had one (TransGo) installed in my '02 C5, which has H/C, 2800 stall, MagnaCharger to name a few. The shifts feel great, quick, not violent - just right. I had a long discussion with the owner of Century Transmission, Mike Kurtz, and he physically showed me the differences in stock parts and the heavy-duty parts he uses for a hi-po rebuild. His rebuild is good to at least 550 rwhp, which is what I'm getting when my tranny needs it since I've got 465 rwhp now. My Best Advice is to have a tranny shop to the shift kit and/or rebuild - NOT a speed/tuner shop Tranny shops don't build hi-po engines and tuners don't build trannys. One last item, to extend the life of the 4L60E, I've got a tranny cooler and had the fluid flushed (including the TC) and replaced with synthetic. Mike said synthetic fluid has a greater molecular shear which is good.
Re: ?'s about shift kits no one has been able to demonstrate track gains, but most people like the SOTP feel of a shift kit. A transgo kit is better then just using an electronic kit to bump line pressure.
The downside is that an improperly installed transgo kit or too much line pressure will lead to a much shorter tranny or converter life. Like Steve said, I would use a tranny shop to install the transgo and have them verify the line pressure when they are done.
