RRbob Posted February 10, 2014 Share Posted February 10, 2014 A slight hi-jack here, but who does reliable work on 700r4's? Give Sean at Top Gear a call. He's a 4L60/65 master and the 700r4 is just the old school version of that. I agree with Jon on this. Link to comment Share on other sites More sharing options...
RRbob Posted February 10, 2014 Share Posted February 10, 2014 Well teh tranny is kaput ! Due to the price of a built replacement, I just ordered a new factory sealed unit thru Ed our good buddy at Coulter on Camelback. We're talking over 2 grand difference in price between built and stock, and thanks to Ed's price theres no way I could afford to go built with this unexpected repair... Ed's thread !!!! Now we're just trying to find out if it comes with a torque converter or not? Sounds like a great deal to me, Dwayne Link to comment Share on other sites More sharing options...
y2krtaf Posted February 10, 2014 Share Posted February 10, 2014 Cudo’s to Ed for hooking you up! Did you ever find out what killed it?My curiosity would have that thing laid out all over my garage LOL! Link to comment Share on other sites More sharing options...
Desertdawg Posted February 10, 2014 Author Share Posted February 10, 2014 Sean at Top Gear said the 6L80's are known to loose the 3/4 snap ring or something like that,I guess it works loose or gets loose over time and kaa-blu-wee...or in my case, screech! Or in ACE terms, Der machinwerks sprung der wonderspring and went der flabberbrokkenn ! Link to comment Share on other sites More sharing options...
MOTV8 Posted February 10, 2014 Share Posted February 10, 2014 And you bought another stock one....? Start saving up for the next one now? Link to comment Share on other sites More sharing options...
Unreal Posted February 10, 2014 Share Posted February 10, 2014 The 6l90 we bought for the Camaro came with a converter. Link to comment Share on other sites More sharing options...
Desertdawg Posted February 10, 2014 Author Share Posted February 10, 2014 Just found out that the one I just ordered comes with a converter too. Thanks! And yes Dean, it's another stock one, my failure is not common. Ask Tom how many passes and miles he has on his! Link to comment Share on other sites More sharing options...
MOTV8 Posted February 10, 2014 Share Posted February 10, 2014 Sean at Top Gear said the 6L80's are known to loose the 3/4 snap ring or something like that, So according to Sean....how common is the issue? It's your car, man. /bookmarked Link to comment Share on other sites More sharing options...
Desertdawg Posted February 10, 2014 Author Share Posted February 10, 2014 He didn't say, but over the 5 years or so that GM has been installing 6L80's he's only worked on a handful... ...compared to the thousands of C5 trannies Link to comment Share on other sites More sharing options...

LastC3 Posted February 10, 2014 Share Posted February 10, 2014 For Tom's Hijack ....... I had mine done by Gary at AZ Precision Trans Center in Mesa .... He's been do our specific 700R4s for ever and does a great job ... he did a stage 2 on mine .... and then added a heavier spring for shifting after the fact ..... and is quite reasonable .... However ... if you're looking for Performance ... I'd have to point to Sean ...... Dawg .... I totally get the cost savings (thx Ed .... you're the man) .... it does cost extra dollars for extra power producing products of a built trans .......... Hope to see ya back on the road soon ......... Link to comment Share on other sites More sharing options...

y2krtaf Posted February 10, 2014 Share Posted February 10, 2014 I was always curious if the improved shifting tunes could cause similar fates. Link to comment Share on other sites More sharing options...
ChadC Posted February 11, 2014 Share Posted February 11, 2014 I was always curious if the improved shifting tunes could cause similar fates...and the aggressive paddle shifting .... and the prolonged 140mph runs imjustsaying Link to comment Share on other sites More sharing options...
HOXXOH Posted February 11, 2014 Share Posted February 11, 2014 If I had to take a guess on causes, I'd think the 3/4 shift under WOT would be the weak link. Especially with a tight (aka stock) converter and a tranny tune that raised the pressure. Link to comment Share on other sites More sharing options...

Desertdawg Posted February 11, 2014 Author Share Posted February 11, 2014 I probably won't ever know what the root cause was, the tranny is out and ready to be handed over to Coulter for the core charge.Yes I have a NicD tune including the tranny.Yes I probably have more WOT 3/4 shifts than anyone here, almost ever trip to Phoenix see's a buck fifty at WOT, I have a passenger that will bitch abou... I mean verify this!In my VIN history I have this line...11/03/2008 149538 # J1000 - PAN AND/OR GASKET - REPLACE 13750 milesThe owners manual says service the tranny at 100,000 for normal use, 50,000 severe duty.There was a TSP for shifting problems that mentions some 3/4 parts and had the dealer pull the tranny apart to fix it, ack!In searching the web I don't see much out there for 6L80 failures. The guys at LPM said when they dropped the valve body there was fiber material and some fine metal on top, looking at the clutch pack there was empty spaces between the disks, there shouldn't be empty spaces there.I'm not pointing fingers at anyone for this, it probably all contributed to the failure. Like I said in the first post there was hints of this coming, missed WOT shifts and delayed engagement from a stop.... Am I happy about this? No, I wish it would have hekd up like Tom's. Am I upgrading? No, I just spent my milk momey on other mods and now I have a couple of home projects to do first. Wish me luck that the replacement tranny lasts at least as long as this one, I already have Jammye bitching abou... I mean asking me to baby it,Yeah, I'm going to baby it right out of LPM's gate, turn right on Cedar st. and romp the shit out of it !!!!! .

HOXXOH Posted February 11, 2014 Share Posted February 11, 2014 Have Nic back off the trans settings a bit and when at WOT ease up for the 3/4 shift. A 3200 stall would be more fun and soften the blow on the trans at the same time. Make sure the cooler lines are flushed real good, so the crap doesn't go right back into the new trans. Insist on the GM fluid, especially to retain the new trans warranty. It's a shame that it happened, but lesser stuff has broken and caused bigger problems.

Do it or yer a wuss. You could have bought my 3600 when I offered it last summer, but you still have time to get a 3200 Yank and have zero install cost. You do know that you could sell that stock converter to recover most of the Yank cost. Just ask Ed how much he'll knock off the bill. If you pass up this opportunity, you'll be kicking yourself later. Link to comment Share on other sites More sharing options...
