I blew my transmission

None of the tranny shops around here want to touch it.? San Diego is a po-dunk town in many respects, especially when it comes to auto performance.? A couple of dealers have said they would do it, but they've said it would be $450-$550, which to me is ridiculous.

$500 may be high, also check on the warrenty as the dealer said that if I bought the tranny it would have a 3/36,000 warrenty, and if GM paid for it, it would have the 12/12,000....

That would be a good one to build up...

If you just want it R&R'd, you could go to most any trans shop.. The PCM/TCM should function ok with it, but it needs to go through a specific programming setup procedure.

If you want to come up to Garden Grove, My bud can do that... But he may want it for his EXT if it's all built up! >:D

Nothing like having a 4L65e spare hanging around!! Damn!

Does it have the hardened parts in it?

It's not built, it's just the 'stock' 4L65E from GMPP. But from what I understand there are hardened parts (i.e. input shaft, etc.), 5-pinion planetaries, etc, so it is a little better unit than the stock 4L60E.

What special programming needs to be done to the 4L65E?

How much would your buddy charge? Is he ASE certified (if so, that means the GMPP 12/12 warrantee starts from the moment the tranny is installed, not when I took delivery last year). PM me if it looks promising.

Call him: http://www.leonstransmission.com Use the Garden Grove #(714) 534-3300. Ask for John.

ASE,  I have no idea, but wouldn't doubt his certification. Some trans shops have a nationwide "membership" network that honor warranty work from other shops. He is in that "network" and they no doubt require this sort of cert.

Mention that "Steve, with the Avalanche" sent you. Advise what you have (2WD, 4WD...)

Yes, the 4L65e has 5 planetaries as opposed to four in the 4L60e. But that hasn't proven to really make it stronger against a disaster such as other hardened parts falling loose into the gears. There are more clutch plates also, however it isn't that likely to have a hardened sunshell or other parts. It's just built to better handle a little more torque. John can change that out and discuss beefing it up, etc. Just ask him!

But remember, there's always a "weak spot" in the drivetrain.

Let me know what you want for the 4L60e...  Ahem... Although I bet the Radix pounded it >:D

BTW, John was wanting to install a Radix in his EXT.. I'll bet it'll get his interest up!

Edit: Typo's :E:
 
Alright, will do, thanks for the info.  Though I have driven like an old man much of the time I've had the blower on, no one seems to believe me.  When I sell the 4L60E it will be as an operational unit - but with no guarantees, of course.

I want the 4L65E for more than just the hardened parts - it comes stock with a 300mm converter meant to stall at 1800 RPM behind a 3500 lb LS6 Corvette, so I'm guessing it will be 2000 RPM's or so behind my 3-ton beast. That would be a nice little upgrade over the 1500 RPM flash/brake stall I'm getting now.
 
Could be, but the 4L65e doesn't mean the parts are hardened, there's just more to grip and to handle the load. (I hope I didn't imply that the parts are hardened! OOPS if so). Maybe a build code will say so, since those are factory-available.

I would say the stall and TCC should pattern close to your torque curve. Likely the LS6 is close to that at the lower RPM's, if not throughout. But the beast is heavier, like you said! Hmmmmm.

I guess that would depend on the mileage. A tear-down and new seals/bushings/bearings would be in order anyway, along with the upgrades. Then there would hopefully be a guarantee (by the builder). So, as long as it's working normally when it's removed, it's a good candidate for a build-up.
 
Have a look at these articles and you will see where I am getting my information:

And this from GMPP web site:
24221888 4L65-E Automatic Transmission
GM Hydramatic has baked even more technology enhancements into the automatic transmission line up with the new 4L65E. This transmission, the latest creation from GM Hydramatic Motorsports, is a four speed, offering all the latest heavy duty components to stand up to the power of the LS6-405 HP Corvette engines. Upgrades like induction hardened turbine input shafts, larger intermediate servo, an additional three-four clutch plate. All go toward accommodating higher engine power output. The 4L65E offers optimized performance, fuel economy and increase durability. This sate-of-the-art transmission features the latest heavy duty components and high tech-electronic controls. The advanced electronics controlling the LS6 engine also manages the 4L65E shift points, providing unparalleled performance and durability, P/N 24221888 also includes the torque converter. (No core charge required on this transmission)
 
I can see in this case, since it has the 24221888 P/N specifically, it's properly equipped.

Just with the quote alone, it defines that...

It's just that using "4L65e" by itself won't define it's "built".

I'll bet that was a pricey item! Since the stock one is around $3K.
 
Damn!
But that's cost + 10%, not list. `Still a lot better than I thought. (Trans only, I presume)

I wouldn't risk dealing with them since they don't support returns though. The site sponsor dealers offer the cost +10% too.
 
Yeah, I've since found a local dealer who will match that vendor, so this is good for going forward.
