Yea mine gxp been fun, and hate to say its two times the car my LS1 Camaro was, sure the camaro was faster but man hated the build quality! Rear end blew of course,5 window motors,drank oil like fine whine, air leaks over 80mph where nuts, damn tq bar and exhaust hit everything under car. Never dreamed I would like a Pontiac better but do.....lol

$4.5k includes a core charge and shipping both ways which Dave screwed me over on. He basically told me 400whp was the limit with the 7/8" chain so I don't know how you guys are getting 600whp out of it.

For a DD yes. For a "Sometimes" track car more than likely. Until you decide to try to catch traction. and can't. on the off chance you do there is still a high probability of chain damage & disintegration. Dave also recommends inspection/replacement as a regular wear maintenance item once modified on a high horsepower application... Not defending or playing against the GXP, TEP, Camaro, or anyone/anything else...but I feel a lot more comfortable about my odds of making 460whp last in the camaro than i do in a GXP... The GXP/MCSS/ISS make wonderful sporty daily drivers...some here have made them exceptionally fast...and hats off... but to me it's about being payment free right now and i can go a lot faster for ~8k in a Z28 than i can for ~303 a month plus 8k cash in a GXP.
When I replied that the rear ends blow in f-bodys the reply was oh no biggy bro, just throw a 9inch in. Okay? So just throw a better trans in our cars right? Nope that's erroneous I guess. Every platform has it's pros and cons.
Cracks me up.
Carry on though.
Let's also think about when your at a point where you need a rear end on a fbody you'll also want the driveshaft u joints and a built trans as well, all of which easily exceed a fully built 4t65
I don't think anyone is in disagreement on what platform would be best to make 460whp... But I find it hilarious when people say "zomg don't get a ls4 car the trannys suck".

Then I wonder the purpose of this thread? Sorry, tranny is junk, comparing it to the 10 bolt is kind of a desperate argument. There is a big price difference of a tranny against a rear differential. There are much better and reliable cars in the same category as these cars.
Carry on....and unsubscribed. Delusional people cracks me up too.

To the OP, I have an 06 GXP and ran a best of 13.61 @ 101.94mph in my only 2 runs down the track with this car. Since this is my winter car, the only mods I've done are a K&N CAI and a Magnaflow exhaust. Does it have more in it? Possibly. I don't think I mastered the launch in just 2 passes. Still on my original transmission at 140,000km too.
I actually didn't plan to buy the car I did end up buying. I don't like the Sport Red Metallic paint very much and it didn't have a sunroof, but the car felt stronger than the others I test drove. Sure the transmissions are a weak link and the car is very heavy, but it is a good car. Don't let the negative slow you down too much. Mine has been completely trouble-free thus far.

Now, if you (the OP) assume that you're going to have this problem, buy the car and put aside money for a built trans, then you're on the right track. But, if you buy one assuming that "with proper maintenance, it will be fine" and ignoring the failure possibility, then you're basically sticking your head in the sand and are likely in a for a rude awakening.
If money is a concern, you can be back up and running after a 10-bolt failure much quicker and cheaper than a 4T65 failure.
Anyway, this is a ****-poor comparison, because a 10-bolt won't fail unless you abuse it in a 6-speed car. Our transmissions fail due to factory design flaws, and many (including mine) have failed regardless of fluid change interval and presence of a cooler.
And for the record, I've owned 3 4th-gen LS1 cars, all with moderate to heavy mods, so I can speak to both cars.
iv been running turbo on my tranny now for few years, new fluid and filter every spring. no issues yet so far (knock on wood ) turbo aside i love having a car that surprises people with the v8, thats part of the consequences, u basically have to understand that i will hapen at sompoint. expect the worst ! so theres no surprises
Thanks to the input on here before I bought my car I bought a warranty and just had the transmission replaced at 50k covered under it. Don't be afraid of buying the car but either put the money aside or buy a comprehensive warranty. I don't know where you live but good snow tires make a world of a difference in the winter too before you go modding.
Now you're talking!
I'd unsubscribe too if I said some dumb crap like you just put in your post. Since you think you know all about wbody trans issues here's a multitude of issue for you to go over...https://ls1tech.com/forums/general-m...roblems-1.html

You folks are in the minority. True, not all LS4 cars will have trans problems, but if you own an LS4 car, YOU ARE MORE LIKELY TO EXPERIENCE A TRANS PROBLEM THAN NOT EXPERIENCE ONE. THIS IS AN IMMUTABLE FACT.

A perfectly good used 10-bolt can be had for a few hundred dollars and can be installed in a couple of hours in a driveway. A used LS4-spec 4T65-HD is anywhere between $500-$1000, with R&R running $600-$1000, and you wouldn't know for sure if it was good unless you took it apart first, or just gambled that you weren't being scammed and installed it anyway. Because of this, and the rarity of the LS4-spec 4T65, most wind up going rebuilt or remanufactured, which ends up being in the $2500-$3000+ range.

This! ^
This too! ^ Just don't get a factory remanufactured trans, as you'll have the same problems, eventually.
Now you're talking!
Hmm...This thread mentions a lot about power window motors, warped brake rotors, water pumps, and the aforementioned 10-bolt. Yes, folks mention various electrical issues and pinion seal leaks, but are you really going to compare these things to a $2500+ LS4 trans job??

Well said. These cars have earned the reputation they deserve, its not the owners fault, its GM. Time has shown that in general they are crappy unreliable cars with a nice engine and...that's about it. Im sorry to say that F-bodies are much more reliable. Its not an opinion, its a FACT.

F-bodies were brought up because ALL platforms have issues. It just depends what you are willing to deal with when the time comes.
Uhmmm....yes and you started it my friend. You felt you needed to desperately defend your argument and tried that road, too bad there was a head on truck coming.
A reminder...posted by you.
Then came this jewel by one of your friends...
Thats what I call...
But hey! Its your money, you want one of these cars?.....good luck, from the bottom of my heart, you're gonna need it.

Yeah, and 10 bolts blow on 4th gens like it's going out of style. Should people steer clear of the platform?

I simply stated that the 10 bolt sucks. Should people shy away of the platform because of that? I don't want one of these cars, I own one already. But thanks for being concerned about my moolah!
Said directly no, clearly implied? **** yes! It was also a damn stupid comparison and you got called for it. The 10 bolt maybe weak but its much more reliable, cheaper and easier to deal with than the excuse for a tranny these crappy cars have. Your comparison may be one of the more retarded things I have read here in a long time. I would never own one not even if its given for free, except for maybe keeping the engine and setting on fire the rest.
