BOSS302, was that on 04 in sig? Care to talk to my dealer about my soft 1-2 shift,...or is it 2-3? Wonder if I should remove tune 1st, along w/ headers back, & CAI. I wouldn't remove all my stuff unless they said that was only way, but at that point, they know how u drive. Oh well, I'm screwed since I have 47k on truck, right?
If that is a brand new truck, that's scary. That would mean they're a bigger than b4.

Now that's funny there(Grenade-80). Tire size will do it as well?

Ya, Will, on my C/K. To u both, & others. I usually find the weak points when I do the stupidest things. On the C/K w/167k miles, 1 day after I did a braketorq, I was on xway in heavy traffic. Motor blew. Replaced w/ more power. Blew stock 700r4, blew 1 built 60E, & grand finale:Blew rear & another built 60E together screwing around. Nowhere near Jim's HP/TQ!

The 4l60e shifts really soft in these trucks, until you swap to a corette or super servo. fastnblu your tranny is probably fine, if its slipping it would act differently.
what kind of tune do you have, that can creat a warrenty problem, but basic bolt ons will not. i hope this helps

oh and suzukibruce you shouldnt need a new rear there are many high horse power truck running that rear end, you need a new locker(non-g80) and maybe some new gears and you will be set

BOSS302

The 1-2 shift on the 4l60 is sloppy anyway, and the only way to somewhat remedy it is w/ a vette or billet servo, or a shift kit (transgo HD2). The 10 bolt can take plenty abuse and power and still keep on goin, it's the G80 Gov-Lock that is the weak link in the chain, it is the nature of it's design. Under low power engagement it will last for a long-time, but if you really get on it.... My tranny was slipping a bit, even w/ increased line pressure and a vette servo, and thats because I bought the truck when I was 17 and drove like it. The rear-end blew and cracked one of the planataries...GM determined this was caused by the abrupt seizure of the G80, thus overstressing...yada, yada, yada. Your trans is probably fine, just don't race every honda you see at a red-light.

If you drive hard, ditch the G80 for a tru-trac or Eaton LSD, the factory ring and pinion should be fine, many guys are running them in high power trucks. Do the servo install, your transmission will thank you. BTW, a tranny cooler is a definite must have.

I said soft, I misspoke, slip(s) prolly is the right word. Didn't do it when I 1st got tune. Local did it so I could dyno it, got rid of speed limiter, tq mgmt. That doesn't help , nor did more mods, or driving it hard! Thanks for input.

Ya, I don't exactly drive it easy. I hit it any time mood strikes, a bad idea for longevity. That stuff is coming...& more. I can't afford trans, @ this time, so parts sit until the day comes. But then...
