I plan on installing the trango kit that will hold 600hp at the crank, also a torque converter with the same spec. I was at the drags today and my truck will not hold a shift to 3 or 4 when locked, I think my 3 and 4 clutches are getting weak. Will this kit get rid of my lazy shifting and alow my edge to perform without backing down power. Let me know please.

You should at least inspect and replace any damaged clutches if you don't install a complete trans kit. Mine are still stock and holding with 160,000km, heavy hauling and lotsa drag racing. They were in perfect condition when I installed my transgo and tripple disc at 108,000km.

You will get better results, but ultimately it will fail too.. Your best bet is to install a complete trans... That will insure you the long haul without having to R&R the trans all over again when you have to redo it...Good luck

:exactly:. You've already done damage so getting a full tranny kit will replace the damaged components and strengthen the tranny even more.

What they have said. A stage 3 suncoast may be a good option for you. Its always better to overbuild though. Better to have too much trans than not enough. Give Mike L. a shout, PM him or his number is in his sig

You'll most likely have to replace the C-3/C-4 clutches and maybe the others as well. I had to replace the C-3 and C-4 and I never limped mine. With the cost of new OEM clutches, you should just buy a complete kit. Not much more money. There are guys running a ton of power through just a transgo/converter, and others that have blown right through that combo. Do some soul searching and level with yourself about the amount of power you'll ever run. It's hard not to keep adding the power, and if thats the case, do it right the first time.

Good luck,

IdahoRob: My transgo/converter seem to hold pretty well so far with the bastard stack... must have one of the good tranny. Will push the enveloppe a little with nitrous this week. I wonder what factors make it hold on some trucks and slip on others with the same power? Any ideas?

A lot of it depends on what the users are using for power adders and how they drive them. Some of the harness boxes offer defueling on locked shifts when they sense slipping. These will help keep your tranny from limping. Others don't offer any tranny protection. 5th gear is a common problem gear since it isn't built to handle as much power as 2nd 3rd and 4th are. I limped mine on a 5th to 4th downshift. I'd done it a bunch of times before without limping the ally but it was only a matter of time. Just my .02

lakingslayer: What I'm asking myself is why just a transgo and converter (and stock clutches) will hold my bastard stack and in some other truck it won't. Believe me; I'm not nice at all with the tranny; 215/5/5 most of the time and of course no defuel on shifts. Drag racing EVERY friday night and heavy hauling all summer long.

Seems to be be like the stock LB7, some will do 230hp and others 270hp... go figure.

Probably because you clutches were in perfect condition when you installed the shift kit and converter. Others may do damage before the upgrades and have weak points to start with. I know if I'd done just a Transgo and converter when I had mine done I'd be looking at going back into it right about now. This could be a cause.

Now that I think about it, the only one that I've read about tearing up a transgo/converter is Juice. PM'ed a few guys running transgo/converter only and are holding extreme and N2O. Pretty impressive. On my 04 there isn't the option of a lockup valve, but I did shim the pump spring. I've finally have a tech II lined up and will see if the transgo/converter is holding pane and N2O. My shifts on the 3/4, 4/5 are great. Tranny acts great around town, but at the track with N2O is where the 1/2, 2/3 shifts go south. Seems like the big kits are having same problems with N2O though.

My driving style/ towing duties/ hotshot might have something to do with it too.

It got me through 7 months or so of some mean abuse:ro)

lakingslayer: I had the "normal" juice (without the attitude) for 2 years before doing the tranny upgrade but never went over 90hp obviously and did the same drag racing and heavy hauling then.

Rob, I think alot of the flaked out shifts are due to the TCM's learing. Its used to one power level and then you throw a bunch of HP on top. Just a theory of mine, I duno though.

When I had mine done My C2's were a little bruised. I had some marks on the steels and the inner clutch area were looking a little burned. The clutches and steels looked like new on the rest of the packs and I could read the S/N on the clutches themselves. I only limped it once but I ran it on 5/5 for a while and drove it like I stole it. I think the stock tranny can hold quite a bit if set up correctly. You only ran the 90hp setting so you probably didn't have enough power to hurt the factory clutches just maybe the TC clutch. The TC really seems to be the weak point of a stock tranny IMHO.

Soooo true. Times drop and shifts improve the more 1/4mile runs I make in a day.
