socom22 Posted June 25, 2009 Report Share Posted June 25, 2009 Well on the way to work this morning i was merging onto a rural highway. Had to cross the highway to go northbound. As I was rolling into the throttle about 1/2 way because there was traffic coming up behind me..... BANG! Truck coasted to a dead stop and the check brake sensor came on. I turned the truck off and started it back up. Engine runs fine, put it in drive, nothing. Put it in reverse and it slowly creeps backwards with a rubbing sound. Well I was 3 miles from work and I couldnt be late so I locked her up and headed to work. I called a local trans shop and they came and towed it to their shop. When I got off I ran by the trans shop as they were dropping the pan. Fluid looked really cherry until we looked into the bottom of the pan. Little metal particles all over the place. F*uck! Well there breaking down tomorrow so I'll update you guys with the verdict to what it was. I was thinking it was the sun gear or the planitary, but would that leave metal shavings in the pan. And will this require a complete rebuild or can they flush the trans and replace the hard parts? Brief history on trans mods: 2800 stall, Zippy shift kit. Rebanded, 2-4 and z-pack clutches. Sorry for the long post.. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted June 25, 2009 Report Share Posted June 25, 2009 (edited) Ouch!........sounds like a broken Reaction Carrier or Reaction Tube, in other words you probably broke a planetary. Be ready for a complete overhaul..... Edited June 25, 2009 by Fireman31 (see edit history) Quote Link to comment Share on other sites More sharing options...
misterp Posted June 25, 2009 Report Share Posted June 25, 2009 Yeah it's going to be ugly and expensive. And I'll bet you a dollar if the zpak has any time on it at all it'll be black and warped - replace all the frictions with Alto high energy (red) and get 9 frictions in the 3/4 stackup. Depending on the band you have it could still be in good shape. Let us know what you find. Mr. P. Quote Link to comment Share on other sites More sharing options...
socom22 Posted June 27, 2009 Author Report Share Posted June 27, 2009 Well guys you were correct, its trashed. I'll post the pics soon. Verdict of break.... snapped rear output shaft/ broke planitay and sheered the sun gear smooth. Trans guys say hes only seen it happen to 650lbs and up cars running 4l60s. Can't believe it. I'm guessing over 2 grand, I'll find out Monday. Quote Link to comment Share on other sites More sharing options...
misterp Posted June 27, 2009 Report Share Posted June 27, 2009 (edited) As we are now SilveradoSS.com supporting vendors we can openly say CALL US we can help you here. Sending you a PM with Dan's phone number (sprayed99). The 4L60 has enough power (by design) to shift hard enough to break itself; the shift kit calibration is critical in these transmissions to get the 1-2 shift right where it won't slip but not too agressive where the transmission grenades itself. Like you I lost an output shaft to improper shift calibration with *bone stock* LQ9 in my truck, and that one hurt bad. Check your PM's, call Dan - our 4L60s serve in daily driven Radix trucks for many forum members here. Mr. P. Edited June 27, 2009 by Mr. P.

socom22 Posted June 28, 2009 Author Report Share Posted June 28, 2009 Thanks for all the input guys! I'll load the pics as soon as I learn how. I'm going to give this trans guy a shot. Taking the advice of some individuals on here, I will be sending my pcm back for alittle shift retuning. It was cool and all to have it yank my head back everytime it shifted (even at low speeds) but I guess its not the best thing for the output shaft.... Damn 06's shitty trans, weird closed loop non enriching SS. Wouldn't buy another truck though. Quote Link to comment Share on other sites More sharing options...

socom22 Posted August 8, 2009 Author Report Share Posted August 8, 2009 F*cking Update!!! So I was out of town for 3 weeks with the truck sitting in the garage. I get back and drive it and it seemed fine. I never sent it back to get retuned thinking after the build it was all good. Wel, I went back by the trans shop to pick up my receipt that I had left from a month ago and BANG. Trucks dead on the side of the road after the 1-2 shift not 1 mile from the shop. They get it back and imidiatly start tearing it down. Now its the GD input shaft and the drum. I pulled the pcm on the spot and sent it back to the tuner. I shoved the stocker in as soon as they had her buttoned up. Runs fine so far but completly a dog with the stock PCM in. I just can't win with this trans...

socom22 Posted August 8, 2009 Author Report Share Posted August 8, 2009 (edited) Jesse at Wait4me. I've had no problems until the trans. I'm kind of caught because Blackbear is doing a group tune in Gulfport, Ms in Sep. And I have to run back to Houston in about a month to renew my registration and inspection sticker. I could have Wheatly do a tune for me while I'm there. Kinda low on cash do to my house in San Diego and the one i'm living in now. Didn't help with me sh*ting 2 grand to have the trans rebuilt last month. Edited August 8, 2009 by texasSS (see edit history) Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted August 8, 2009 Report Share Posted August 8, 2009 What broke the first time? Quote Link to comment Share on other sites More sharing options...
socom22 Posted August 9, 2009 Author Report Share Posted August 9, 2009 The output shaft snapped at the oilhole. Part of the shaft spun in the planitary and tore all the parts attached to the output shaft. Quote Link to comment Share on other sites More sharing options...

socom22 Posted August 9, 2009 Author Report Share Posted August 9, 2009 Cai, exhaust, headers, wires, 2800 stall, zippy shift kit. 2/2 drop,nitto tires and a custom tune. It's an 06', 2wd and it only has 40,000 miles. I use it as a dd which is about a 20 min drive on open hwy. I usually get on it 2 or 3 times a week but not from a dead stop. Usually on the on ramp and on the highway. My wife's getting pissed because I keep dumping money in the SS. Any help on what it could be would help guys..
