#629 of 1489 2000 Silverado Z71 Shift Problems by bhodgden

Jun 01, 2010 (7:03 am)

Hello,
I have a 2000 Chevy Silverado 1500 Z71 with 5.3L. I had a problem arise a year ago. Whenever I would drive on a long trip and then come into a town, when I would take back off from a stop sign or light, the transmission would shift hard into second and third gears. I had the transmission flushed and filters changed. They found one of the solenoids broken ($5 replacement) in the transmission. Well this past weekend I was pulling my boat back from the lake when it started to do the exact same thing. Is the transmission fried? I need to find something out soon. I don't want to pull my camper or boat anymore if the transmission is going out.

I am getting a check engine light, on my digital screen I am getting a Hot Transmission, and my truck is shifting harder than usual. People have been telling me that it is my TCC solenoid, and one guy said that wasn't it? What is wrong

I have a 2007 GMC Sierra 1500 Z71 with 48,000 miles on it. The transmission has some sort of glitched as I approach or depart a light or stop sign. Instead of a smooth shift either up or down I feel a sudden locking of the transmission or something of the sort resulting in a "sudden jerk". This has nothing to do with the locking differential which works well in slippery road conditions
When I purchased the truck apparently it came with a yoke that was not sufficiently greased as many times this manifested itself as though I had been rear-ended lightly when stopped at a light. The GM dealer greased the yoke and this helped. But now I have this problem. Could it be that the yoke has to be greased again ? Does the yoke have to be greased several times over the life of the vehicle ?
I have checked the fluid level and it id right within specs and the color is still bright red. I've never used the truck to tow anything. Any Ideas ?

First thing that would come to my mind, if its intermittent would be pressure control solenoid. High line pressure would cause it to be loud and hard maybe thunk.

#636 of 1489 01 4.3 1500 misfires by filthyanimal

Jun 10, 2010 (10:43 am)

Hi, I am going to say what a pain.
I have a 01 1500 4.3 po300 flashing engine light. let me say I have a scanner and consider myself to be somewhat knowledgeable. but I am looking for ideas.
I have po 300 right bank 2 4 6 misfires engine obviously lacks power. barely runs . I have -35 degrees cam retard. Wont run long or fast enough to do crk learn. I think it is symptom of misfire not cause. I have pulled exhasut off pass side to eliminate the cat. doesnt change it without cat c onected. I got it to run long enough to set o2 code but it was for the heater circuit. I have read that the injectors should have 11-14 ohms resistance if checked at the pins in the upper plenum Anyone heard that. Mine do not have between 5 - 8 ohms. on the 6.. Is it likely all 6 injectors went bad at once. the fuel trim is being cut off on the even bank -25% while odd side is dumping +25%. I want to believe its come down to pcm ,spider,02's, possibly maf but it doesnt change and has comparable readings to my v8 burban. i am open to ideas distributor, but that would explain timing but not dumping of fuel
fuel pressure is koeo 62psi, and 58 barely running. Thanks

My '99 Silverado has suddenly lost reverse. All the drive gears work fine & the tranny fluid is OK so what would cause this? At over 225,000 miles is this the beginning of the end for my tranny?

#638 of 1489 04 Chevy Silverado Z71 by ftosrod

Jun 15, 2010 (9:17 am)

I have a 04 Silverado and right after my truck passed 70,000 miles, it began not engaging in reverse. This doesn't happen every time but probably 3-4 times a month. One thing that does happen every time is it shifts really hard when I put it in reverse. It also makes a loud noise, like it's hunkering down. This is very frusting because I bought this truck hoping that I would not have to worry about making expensive repairs! I am thinking I will have to buy a new transmission by the end of the year! Does anyone have any ides what is causing this? I really don't want to trade my truck in if this is a sign to other things that might be coming! Thanks everyone!
