Thanks for the input. I was just searching around an an NV4500 came up locally. 2WD unit, unknown condition, but its the 93 GM with the tall first gear. The case is completely covered in dirt/rust..... Asking price..... $1,500 firm. I'm sure that will sell just as quickly as the $35,000 square...

The 4L80E is one tough transmission. Maybe I should leave it alone. And just for the sake of information gathering, since adjusting the TCC lock-up speed up 1mph I have not been able to replicate the issue. I’ve driven several hours both city and some quiet back-country highway. Everything is...

I’m enjoying the 4L80E with 37’s. 55-70mph is comfortable all day. The more I think about it, and the more I zero in on what I want this truck to be, the more I want to swap in an early NV4500. I used to be all about modernizing but now I just hate computer controlled stuff. I’m contemplating...

Yes but not all the time. If it does it again I will hit the parking brake and take my foot off the pedal to check. Here's my brake booster situation: The hydraboost is a new rebuilt unit. I went through several before I got a good one. I disassembled it and sent it out to have it ported and...

Thanks, that's about what I'm seeing but mine does tend to creep upward until lockup. I'll going play around with it today. Went to install a new #2 alternator this morning only to realize it was missing a post.... not sure how I didn't catch that before.. I'll do some testing later once its...

Any idea what temp your transmission normally runs? I set the TC to lock at 55 and there seems to be a more linear acceleration now; however, it did increase temps.

So yesterday I went into the transmission controller and changed the TCC value from 44mph to 45mph. Now the converter locks at exactly 45mph, I can hear and feel it. The TC unlocks at around 35mph while at throttle idle during decel. I could not replicate the issue... Perhaps it was just a...

The lines run into the factory cooler on the radiator and then down to a secondary cooler below the radiator. It’s not ideal but I don’t really tow, the M1008 is my daily driver.

exactly what I was thinking shortly after I made this post. That’s for the troubleshooting advice. I have very little hands on experience with automatic transmissions

Engine runs perfect while idling in neutral or park. Runs great while underway. The second I come to a full stop while in gear the RPM’s dip and it starts shuddering/shaking. Any ideas? Doesn’t happen all the time. Can’t tell if it’s a miss or what’s going on, it sounds really odd. Pop it into...
