    Will the 4L80E shudder at highway speed

    Ok so I’m sure you haven’t a site dry thing I’ve posted so I’ve rebuilt this frint end from the frame out put totally different wheels and tires on it and nothing has changed so I’ve started with tranny mount motor mounts and what felt to me like a possible trans shudder and yes it feels like a...

    Will the 4L80E shudder at highway speed

    Im not looking for gas engine information I’m looking for transmission information I don’t think it will make any difference what motor is in front of it

    Will the 4L80E shudder at highway speed

    I looked in store and online and didn’t find anything that would read that much info from the OBD-II though there are a lot of other options throughout the internet so now I have homework. I’ll try the brake switch being disconnected though. I still in the back of my head think it’s the front...

    I can afford that one thank you

    Will the 4L80E shudder at highway speed

    I do my best to keep it running tip top since it is a big block and gas is expensive. It eats rotor bug and distributor caps aswell. I replace them every six months like clock work or I pay at the pump. I do appreciate your input and thoughtfulness greatly

    Will the 4L80E shudder at highway speed

    Hey I appreciate you sharing this with me. I never would’ve imagined that it was only another $20 there about to have them do it. I’ll definitely check into that. I’m going to see if I can find someone local that has this reader and will spend an hour or so in my truck one day for a little bit...

    Well maybe you wouldn’t… you can balance tires without weights by rotating the tire on the wheel if you have the tools available. I’ve also cut down a drive shaft ground the old weld off the cup that is what the ears for the u joint are connected to or formed to however you would say it anyway...

    Where can I find this scanner and what is the cost of performing this test?

    Where can I find this scanner / screen to use while driving you’ve referred to. How expensive is this test going to be?

    Will the 4L80E shudder at highway speed

    Well this may cause you think I’m dumb and when it comes to how a trans functions I would have to agree but I had to google TCC and PCM. So now that I’m up to speed I assume if this was the issue I would have a service engine light to get the OBD-II code P-0743 for TCC issues and I have no codes.

    Will the 4L80E shudder at highway speed

    I’ve changed wheels and tires completely to see if it was a bent or balance issue I’ll check more into the issue coming from the rear. Inside the truck it feels like it’s in the front or even-in front passenger lately I’ve felt like it feels more centered in the truck is why I question the trans...

    oh man!!!… I really hope it’s not a spun bearing I’m not financially able to do a build right now being a single dad of two without any assistance or even child support. ( it drives me crazy all these worthless people that get state assistance but if you work hard and try to make something of...

    I’ve replaced the tranny mount twice. Once when I first got the truck almost 4 years ago and recently. This truck doesn’t have a carrier on the driveshaft. I appreciate the information though.

    If the torque converter were slipping wouldn’t I notice that in unusually high rpm while driving?

    Hey newb here just registered… I have a 96 GMC C2500 suburban. There were two of the 3/4 ton made from my understanding. The light one has a GVW of 7800lbs and the heavy has a GVW of 8600lbs. Mine is the heavy and unless I’ve been misinformed only trucks over 8000lbs came with the good stuff...
