Texas is so big, it makes it hard for people to get together. And it's not easy for people from other states sometimes to grasp how damn big this lone star state is LOL. I've had to deal with that many times in my jobs, when out of towners don't realize that it can take 2 or 3 hours to get across Houston. Let alone major city to another major city.....
Mom and I have to travel between stores a lot for our work. From southeast Houston to the SW suburbs, sometimes all in the same day. One time it'll take 30 minutes from gulf freeway to south main or Bellaire, next time it's an hour. And this is on the surface streets, no freeway driving. Freeways are too crazy here, between construction and stupid drivers.

Yes doing service calls all over Houston I agree

If I drove it would be 5+ hours. I'm old and drive like it!

Oh, so if you really want an up grade, why not a 4L80E. But its not really needed.

I disagree personally. Stock 60E failed at 38K. Built 4L65E with lots of goodies died in 40K. Stock trans behind a stock 350 Vortec. The built trans behind a cammed and tuned L31 with shorty headers. Then again its a heavy van. GM put the 4L80E behind a 4.3 TBI when the GVW exceeded a certain point. All the 8-lug Express/Savanna vans had a 4L80E even the 2500s that came with a 4.3 or 4.8. HUGE difference in transmission stress between a lightweight sports car and a 5,000+ lbs truck. The truck will kill the same trans with much less power than the car. Trans is under more stress moving the truck around even in normal driving.

What you doing with your van for a trans to fail at 35,000 and 40,000 miles? Pulling a full size tractor, or, who ever is doing your trans work need to be fired. Yes a 80E will out pull a 60E. The trans is a larger unit. Bigger clutches, bigger bands, ECT. Like I said before,what are you doing with truck. My first 60E lasted to 275,000 miles. The one I have now has 250,000+, and its still going fine. It may quit tomorrow, IDK. Then does the ECM need to be flashed for the 80E?

I’ve had 3 of the 60e units...one in my 95, the other 2 in both my 2005 trucks, both those with well over 250,000 miles. And I USE my trucks as such. Yeah an 80e would be an upgrade but then again I’ve put a half million miles on 60e transmissions with no ill effects so why bother

Driving it mostly on the highway. ZERO towing. Did not even have a hitch on it until after I put the 4L85E in it. First trans failure at 38K was the factory GM trans.

PCM does need to be flashed.

I let a pro do the spider.The motor was shaking at idle/600rpm before it started misfiring. I pulled and cleaned EGR weeks ago as I heard it could cause rough idle etc. It was still shaking a bit at idle when I drove it home tonight, half way home the engine light came on.Checked the code and it was a P1404. I popped the hood and looked at the EGR.I noticed the EGR was touching the heater hose. I had rotated it 180* ! I also found that the gasket had slipped out while I bolted down the EGR w the sun going down, weeks ago. Got a new gasket and rotated the EGR. Now it idles 700/750 and the shake at idle is gone.I guess I'm getting to old to wrench

My old battery died after the engine started misfireing and I replaced it. The first time i checked the mpg after the new spider around 100 miles it was 12.3 ! Before the misfire it was close to 15 city/highway. Checked it last night at about 250 miles on the new spider and it was 17.36! All city!

Kinda lost track of what you did from the beginning... I think you replaced the fuel pump and recently the spider injectors? Seems like truck runs well now and with improved fuel mileage!? Except for the EGR code, right? Seems like a move in the right direction!

EGR on these are very simple and easy to check. Look into here: https://easyautodiagnostics.com/gm/4.3L-5.0L-5.7L/egr-valve-tests-1
