jc04ss Posted July 15, 2012 Report Share Posted July 15, 2012 Hey all! Its been awhile since I have been on here. Wondering if anyone else has had this issue.... I have a '04 SS, awd, 51,000 miles, everything stock except for outlaw cold air intake. Had it street tuned w/HP tuner (at around 30.000 miles) by a local speed shop here in Wash St. around 2006-2007. The tune is great....except for occasionally the trans will seem to "stick" for around 5-6 seconds going from 1st to 2nd. I mean it is stuck for that time no matter what you do. I usually let off on the throttle until it engages. It started doing it about a month after the tune. I took it back to the shop, but it would'nt mimic the problem again. A couple years ago had a trans shop check the accumalators (?) or shift solinoids (?) they were fine. Then it starts happening again?? When I had the tune done I had them zero out the Torque Mgt. They adjusted shift points and barely raised the the line pressure. It does not shift hard, but nice and firm. Acts like a basic shift kit. It does this about once a month, maybe twice a month?? Any weather conditions and any driving condictions, but its from stop to start. Anybody else had this problem? Any ideas on fixes?? Thanks!!!

El Chivo 1986 Posted July 15, 2012 Report Share Posted July 15, 2012 What can i say man, im already on my 4 tranny, hope u dont go dat way too,man. Try out on the valve body the accumulator maybe its getting stuck. Its a plastic one, and when u do a shift kit its rec. you u put an bellit one or aluminum one.

canadianVRss Posted July 15, 2012 Report Share Posted July 15, 2012 Can you rev it and it won't move? Quote Link to comment Share on other sites More sharing options...
jc04ss Posted July 16, 2012 Author Report Share Posted July 16, 2012 Can you rev it and it won't move? Not sure what you mean? It does it when I start to go from a stop or a stop light. It gets "stuck" in first gear for around 5-6 seconds and then shifts to second gear. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted July 17, 2012 Report Share Posted July 17, 2012 He means when it stays in gear and holds up if you were to hit the gas will it force itself to shift, or does it still hang up. Both my 04 and my 03 Sss trucks do this from time to time and they are stock. The only thing that fixed it was having the dealer put in a tune from the newer silverados.

No, it stays in gear no matter if you hit the gas or not. It eventually shifts after around 5-7 seconds. What year of Silverado did you tune your other trucks to?? I might look into that.

lgowen343 Posted July 18, 2012 Report Share Posted July 18, 2012 I had that problem when mine was stock. When I put the Transgo shift kit and Corvette billet servos and the Wheatley tune in, it went away. It now slams Hard into 2nd when half way on the gas. Nice feeling. I have 140k on my trans and no problems so I dont know if that helped. But you can get Corvette servos on ebay for really cheap. And they are not hard to install yourself.

2006SilverSS Posted July 18, 2012 Report Share Posted July 18, 2012 I've had that same issue since I bought the truck, I now have a shift kit and all (have for a few years) and my truck still does it randomly. Quote Link to comment Share on other sites More sharing options...
jc04ss Posted July 18, 2012 Author Report Share Posted July 18, 2012 When you guys had your tune done, did they leave in any Torque Management?? or zero it out?? I was checking out those corvette servos a few years back. Anyone put those in without a shift kit?? Quote Link to comment Share on other sites More sharing options...

Looks like I still have Torque Management on mine (just looked at it), are you thinking that's causing some of that issue? If so why? Or was that just a general question thrown out there? haha.

jc04ss Posted July 18, 2012 Author Report Share Posted July 18, 2012 Back when I was looking into doing a tune (5 years ago) between reading and asking guys on this forum and doing my own research, some were leaving 50% - 20% Torque Mgt. Talking with the shop that did my tune they suggested zeroing out my Torque Mgt to get the most benefit of mimicing a mild shift kit. Which it did. What I noticed with no Torque Mgt is that there is no overlap between shifts and I was wondering if that is causing accumalator (sp?) issues at times or soliniod (sp?) issues. I did have a trans shop drop the pan in the trans (4 yrs ago) and check out the soleniods and had them replaced, but it still happens. I compare the overlap with my wifes '08 Trailblazer SS, bone stock. The Torques Mgt really hampers that trans. But it sitll runs like a raped ape After thinking about this tune/trans deal, I remembered that sometimes when I am slowing down in traffic and its in 2nd and has to downshift (under normal throttle or punchin' it) it wil stick as well. Thats why I was wondering if anybody had some percentage of Torque Mgt added back into thier tune?? Thanks for the feedback guys!! Keep it coming, maybe we'll get this figured out.

Fireman31 Posted July 19, 2012 Report Share Posted July 19, 2012 No Torque Management without a shift kit was bad news I thought. Aren't you were supposed to leave a percentage? We really need Zippy to chime in here...... Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted July 19, 2012 Report Share Posted July 19, 2012 You need to leave some torque management in a 4l60 unless its built or else your tranny will not last very long. Quote Link to comment Share on other sites More sharing options...

Bingo, 2nd to 1st shift and from idle to 1st. Feels like a brake caliper is locked up and then bang away you go. Quote Link to comment Share on other sites More sharing options...
