    Another 4L80E Question from a GMT400 Newbie

    Gotcha. I'm running 4.10s with stock tires (265/75/15) RPM's plays a role I'm sure. Sent from my SAMSUNG-SM-G920A using Tapatalk

    Another 4L80E Question from a GMT400 Newbie

    I'd like to do some more research. You'd think they'd lock up at the same time, I'm sure we both have 4.10s. I don't think anything else would play a factor in it. Sent from my SAMSUNG-SM-G920A using Tapatalk

    Another 4L80E Question from a GMT400 Newbie

    My exhaust makes all my shifts sound weird too, PO had stock exhaust all the way to two glass packs with no tips on them or anything. Sent from my SAMSUNG-SM-G920A using Tapatalk

    Another 4L80E Question from a GMT400 Newbie

    Actually, I'm positive that it locks up before 58 MPH because my ride to work is 55 MPH speed limit and it locks up. I can cruise 55-60 at around 1900 RPM's. Give or take a little. Sent from my SAMSUNG-SM-G920A using Tapatalk

    Another 4L80E Question from a GMT400 Newbie

    I think mine locks up before 58 MPH. I'd have to drive it and see. Could that be caused by a wiring issue or would it point to a straight torque converter problem? Sent from my SAMSUNG-SM-G920A using Tapatalk

    Another 4L80E Question from a GMT400 Newbie

    I've had my truck for around three weeks now, and it's the first vehicle I've ever owned with a 4L80E. I've owned a couple S10 Blazers with the 4L60E but that's the closest I've been to one. Just came from a Dodge Durango with an automatic and it has some weird shifts to it. (What do you expect...

    Oil Pressure Question

    It's really an across the board question. I've got so many different answers because this isn't the only place I've posted it. I've done Google searches and all kinds of stuff. It appears that if you are anywhere between 20-40 at a hot idle and 40-60 at hot WOT, you are doing good. Chevrolet...

    Oil Pressure Question

    I'd like to check and see if the intake is leaking. Radiator was a tad low along with the reserve tank when I bought it. It had to have went somewhere. I filled it, but haven't driven it since so I'm not sure if it's using it or what. Oil doesn't appear to have water in it. Sent from my...

    Oil Pressure Question

    That's what strikes me as weird. The truck has 116K on it, it's not running dexcool anymore. Oil is full, looks decent, but PO said it was due for an oil change. He said he has owned the truck for roughly a year and that's the way it's been the whole time. I have done some google searches on the...

    Oil Pressure Question

    I'm coming from a Ford truck that basically didn't move regardless of RPM's. It was more less a dummy gauge that wouldn't move unless it went below a certain PSI. Guess that's why I never worried about it until buying this chevy. Sent from my SAMSUNG-SM-G920A using Tapatalk

    Oil Pressure Question

    Mine runs about 20-25 at a hot idle, and 40-45 when in the throttle. I just bought the truck, PO said it was due for an oil change so we will see if that changes it at all. Sent from my SAMSUNG-SM-G920A using Tapatalk

    Factory Radio Question 2000 3500... Pics Attatched

    Previous owner had an aftermarket head unit in the truck, I want to put a stock one back in it, but this is all I was left with as far as an antenna goes. Does anyone know where I can buy an adapter or something to make this work? Sent from my SAMSUNG-SM-G920A using Tapatalk

    4L80E Concerns?

    I just bought it, but I know the previous owner on a personal level. He's owned the truck for about a year and he bought it from the original owner. The truck has been meticulously maintained. Transmission fluid looks and smells great. It has 116,xxx miles on it. Sent from my iPhone using...

    4L80E Concerns?

    New GMT 400 owner here and I have a few questions/concerns. First and foremost, I have a fear of automatic transmissions because they can be fine one day and down to he next so I guess that's where most of my concerns are coming from. My truck has the 5.7 (350) with the 4L80E transmission...
