I'm not sure about that port, I'll check and get back to you. Make it a great day!

Dustin, no dumb questions, and I’m not sure myself. Back in March the good folks on the forum gave me some interesting answers to what might be causing my problem (lack of the ability to shift between the automatic gears, which was an intermittent problem). I’ll hopefully have a functioning...

Interestingly, after weeks and weeks of waiting, I had a qualified mechanic check this out and all grounds, ignition, etc., seem to be functioning fine. The 1-2 and 3–4 shift modules were replaced but the vehicle still will not shift past second while in drive. He thinks next an answer may be to...

Very helpful guys, I really appreciate it. Hopefully, the 4L80E I've got will hold up for a few more years. I've found someone to work on it next week who is very familiar with them. I'll keep you posted.

PS: can anyone recommend an automatic transmission, besides the 4L80E, that is affordable, very heavy duty, reliable, and suitable for a class C RV that weighs about 10,000 pounds fully loaded? It could be connected to my current Chevy 350 motor, or an LS motor in the future.

Sounds like meanness in a small engine package!

Husker, I replaced the original 350 ci about 3-4 years ago. That motor had about 93,000 miles on it, and although ran fine, was just flat tired and had maybe 200-225 horses; big hills were a big problem. Those 1993 heads were just horrible. It was a two bolt main motor with throttle body...

My vehicle is a 22' Class C RV built on a 1993 Chevy G30 one ton van chassis. This RV has been in my family since new in January 1994. The RV has been to 46 states and the north slope of Alaska twice. My Dad gave me the vehicle in 2007. Our most recent trip was to the Daytona 500 in February, 2022.

Thanks Husker, I was just able to pick up a used manual on EBay for $20.00. It covers the G30 van from 1968 to 1995; mines a 1993 G30 chassis. Given the difficulty I've had in finding someone willing to work on a small RV, it's clear that I'm going to have to start doing some of the simpler...

D, this is helpful as well, very helpful, and I appreciate it. I think I'll certainly start with the ignition switch and see what happens. I've got in-laws that live between New Berlin and La Vernia, so I know your area. Best, Paul

Marty, I love getting my hands dirty when I think I can reasonably complete the task. I’m handy, but certainly no mechanic. However, I do not have a shop manual for a 1993 Chevy G30 van. That’s going to be my first “investment” later this week. Once again, I really appreciate everyones...

Very helpful Sir, and I really appreciate your time with such a great response! I'm having a bit of a hard time finding a mechanic that wants to deal with these issues, but one will make themselves known soon I'm sure of it. Best regards, Paul

Marty, I appreciate the quick response. Very helpful and certainly worth a look and a try. Anything beginning with “free” is a great first option. I’ll keep you posted as to the result of this attempt. Make it a great weekend! Paul

Howdy folks, I've seen some posts pertaining to this transmission, and mine is acting strangely, consequently, I have some questions for anyone that can offer some advice/wisdom. Here are the particulars of the vehicle: - 1993 22' Class C RV on Chevy G30 one ton van chassis; fully loaded...
