Replying to: Pard (Dec 16, 2008 5:58 am) I have the same trouble with my 2005, Z71, with babied 20,000 miles.... seems to start in third if you let it. If i shut if off for a few minutes and re start the truck it will work fine. I'm thinking one of the servos is sticking ,but like you mentioned the problem is intermittent...
#373 of 506 Removing transmission pan on 04 Sub by jamonett Dec 20, 2008 (8:19 pm)
Hello everyone,    I am having a very difficult time removing the transmission pan on my 04 Suburban. The bracket that holds the shift cable is blocking me from dropping the pan down. I have tried bending it out of the way, but that doesn't work as it is too stiff to bend it very far. And I don't want to break it off of the transmission case. It looks like I need to drop/remove the exhaust Y and then I can "fold" the pan down at a 90 degree angle and slip it out from behind the bracket.   Any suggestions?   Thank you in advance for any help.   John Replies to this message: obyone (Dec 20, 2008 10:15 pm) 2001silverado (Mar 15, 2009 7:44 am) bumperdude (Mar 15, 2009 8:35 am)

#375 of 506 4L80-E Auto Trans Wire Harness Fluid Leak by JParke Dec 21, 2008 (2:43 am)
Trans fluid is leaking through the wire harness plug. What is the cause. Is replacing the harness the only remedy? Can the fluid cause a short circuit at the plug. What seals the plug on the inside of the case? How difficult is it to replace the harness?   Jim

#377 of 506 2004 silverado 4th gear problems by geez150 Dec 26, 2008 (8:59 am)
My 2004 chevy silverado 5.3 4x4 is having tranny trouble. After the tranny shifts into 4th gear and i'm doing about 40-55mph and in the rpm range of 1500-1800 it starts bucking bad. If i either speed up to say 60 it goes away or if i slow down it goes away. The STEALER has no clue! Any help would be great!
#378 of 506 tranny clunking by freewheelin1 Jan 03, 2009 (2:28 pm)
When I accelerate from a red light sometimes i hear a clunking from the tranny going into second gear and less so into third. I thought i read somewhere that the gear changing in Sierra's are noisy.... is this the case or should i consult someone that the tranny might be going.... I JUST bought it ...an 05 GMC Sierra 4x4 34,796 miles. It seems to occur more often when i accelerate a bit harder.
#379 of 506 2001 2500 4L80E shifting problem by bluedroptop Jan 03, 2009 (8:04 pm)
When the trans. temp. is between 100 and 150 degrees, the trans. shifts hard from 1st to 2nd. This isn't a constant problem, just occasional. Otherwise the trans. works fine. Any suggestion as to what is causing this problem, or remedies. Any info will be helpful.   Thanks, bluedroptop

update on my 2004 chevy silverado 5.3 4x4 with 31,000 on it, picking it up for the stealer tomorrow, they replaced the torque converter on it, so hopefully the problem will be gone
