#679 of 1521 Delay in Trans? shifting in R
Sep 13, 2010 (5:01 pm)
I have a 2000 Chevy Silverado 1500 5.3 liter V8. With 148,000 miles on it. I have a rebuild trans in it. About a month ago I it started delaying going in Reverse. I fine it does it when it been running for a long time and in drive for a while. When I go to put it in R it light up on the dash that its in R and my back up lights are on. If I take my foot of the brake to give it gas to go back wards it will start rolling forward. If I gi ve it a little bit of gas it will make a lond clunk from underneath the truck and then it will go back wards. Its been to my trans place and they did fine a leak and fixed it. But its still doing and its starting to bother me as I use this truck to pull a horse trailer. And when it does it, It screws every thing up. I love my Chevy But wish I can afford a new one with more torque and diesel.

i have read all the posts my problems are a little different. i have no reverse or 2nd gear, truck runs great on highway 75 mph 3000 rpm. shifting from 1st i have to get truck up to 35 mph before it shifts into what i think is 3rd gear. does anyone else have this problem or heard of this?

A Burned Out Overdrive Band Normally Causes You To Have No Reverse Or Second Gear. Also The Servo That Pushes The Band May Have Something Wrong With It. " HOPE THIS HELPS"

thanks, jbh40. i am not much of a tranny guy so i have a couple of more questions. i presume that either one of them means i need a new tranny. so with that said do you happen to know which tranny i have in my truck the 4l60e or the 4l80e? if i have the 4l60e is it possible to put the 4l80e in as a replacement? i have heard it is a little beefier tranny. again thanks for the info it really did help.

You have the 4L-60E. I'd check around and see if you can fit a 6L-60E before looking at a 4L-80E. Just my opinion.

hi, if you thought the trans fluid was oil that indicates to me that it is burnt, when a clutch pack burns out it will cook the oil. 35 mph is the usual shift point for 2nd to 3rd at mid throttle, what you can try is to push it to 40 to 45 mph at heavy throttle then let all the way off and see if it shifts into 4th gear that will let you know if you have a pack burnt out. as for being 1 qt low that should not affect the operation there is a built in cushion, even so it is still a good idea to keep the fluid levels in their operating ranges as indicated on the dip sticks. the year and engine displacement would help even further.

The 4L60-E is what you have. The 4L80-E will not fit your transfer case,Bolt pattern is different and the 4L80-E has a larger output shaft. It would be easier to build your 4L60-E with heavier upgraded parts to make it beefier. "Good Luck"
#686 of 1521 6 speed transmission
Sep 24, 2010 (7:57 am)
My 2008 Z71 4wd with 28000 mi tries to shift from 5 to OD at 1200 to 1400 or so but cant seem to make up its mind and goes back and forth from 5 to 6.. Problem started at 26000mi The result is a chug at that rpm range and 40mph. It happens at light throttle. with a load it doesnt do this. Drivability is not a particular problem just annoying. I have had the transmission taken down and checked. no problems found. The conclusion is that the software says shift to 6 to save gas and for better mileage.? Maybe related to 10% ethanol gas? No software change is available says dealer.

i have the same issue with my 2010 sierra 2wd. took 1 truck back because of this.
now with 4800 miles this one is doing it.
dealer says there is no problem. BS! unfortunately it is intermittent and hard to diagnose but, it definitely is not right. anybody heard of any solutions to this issue?
#688 of 1521 95 C2500 4L80E- NO REVERSE!!!???
Sep 25, 2010 (2:03 pm)
I've got a 6.5 turbo diesel, type "s"; Ext cab; 2wD.
Got in one morning and no reverse.
Fluid was burnt.
Changed fluid and seal -still no reverse -nothing at all!
All other gears work perfectly.
I'm told the reverse band is fried, I'm hoping someone gives me a much cheaper solution.
If it is dead and I need to get a used one, I'm told by the local dealership that ONLY trannys from this list (no exceptions) will fit in my truck:
-6.5 Diesel (maybe a different sized diesel, I'm not certain on that)
From what I understand, it can't come from a suburban, van, or anything other than from above list.
Can someone confirm this for me?
Also, I know this is wishful thinking, is there anything in the steering wheel/column that electronically controls reverse. There's something loose, sounds like it's coming from the steering wheel itself, that's rolling around and klunking everytime I turn the wheel.
