07 up Suburban trans info needed
We are looking for an 07 up suburban 4x4 for my wife and need some info from those who either have one or are a tech at a dealership.
My mother has an 07 Suburban 1500 2wd and has already had the trans replaced under warranty once. Actually it took the dealership 3 tranmissions from GM to get one that worked. The first replacement trans wouldn't even get the truck off the rack, The second dropped a gear on the tech during the test drive, and the third trans now has less than 50,000 on it and is acting up. This is unacceptable to me, although I feel GM has never been able to build a decent OD trans. Ok the 4l80 or whichever one is the turbo 400 with an OD seems to be alright. Saying all that to say I see the '10 and up Subs have a 6 speed auto trans are they holding up better? What is everyones experience with them? Jeff Lee |

Re: 07 up Suburban trans info needed
Sorry about the bad luck on your mom's Burb, If you ever need one built right PM me.
'07-'08 1500 Burb would have a 4L60E, They generally last at least 150K some go a lot further. Very simple transmissions with a lot of aftermarket support for factory weaknesses. '07-'08 2500 Burb's have 4L80E's....Stout units! '09 & up have 6L80E's, I have mixed feelings about them, Shift flares, Broken drums, Funky programing. As they age....These may be worse than a 4L60E ever was & a lot more expensive to fix. Time will tell...... For now they are holding up well though. |

Thanks for the info clinebarger. I would really like to find a 3/4 ton but they are rather hard to find here and when you do find one they are proud of them. I wish I was closer to your area I can find them out there at reasonable prices.

Re: 07 up Suburban trans info needed
sounds like the guys installing them doesn't have the right software uploaded and it's grenading itself. Or there is a poor connection at trans harness. Either way, we are only getting part of the story. I find it hard to believe GM is sending out bad transmissions.
<sarcasm ; on> Yeah, 4L60E is junk. That's why mine has 160,000 miles and is still strong. <sarcasm ; off>
