Transmission Upgrade Almost Complete...

[CONRAD II]

I just got off the phone withn the transmission shop that has my rig. I have upgraded the stock tranny to a heavier duty built 4L80E. That was the tranny that GM used on their bigger pickups and H1's untill the Allison tranny came into play. From all the research I've done I can't find anyone else who had done an entire tranny upgrade and swap. Anyway, everything is just about complete and I should be able to pick it up around friday. If anyone is interested I can show the entire list of upgrades and new parts, gears, flywheel, torque converter etc....

List of parts and even an ABC order of work. Not likely the tranny guys will give to much detail. Any info would be cool.

I have a couple of tranny companies one in the south and other in north. I'm just always checking on what is being done in other areas.

Actually the transmission guys are really cool and have documented the entire conversion. I will have pics as soon as I get my rig back but I will list all of the new parts as ASAP

Mate, I'm interested. Can you let me know if you can shift it like a tiptronic and will it be lockable in each gear?

I really don't see any need for a tiptronic setup so I never really investigated the possibility. I might have looked into that setup if I were driving a lambo, but I just want a bullet proof reliable transmission!!!

Mate, Mine is constantly shifting down, sometimes as far as 2nd on the open road and when it's tiptronic or selectronic it stays in the gear one's selected i.e. Top gear, god knows it's got the HP / Torque to cope with minor hills. I've only clocked up 11500 Km (7145 M ) since I've had it and it's already bugging me. Locking it in the bush is the shot as it makes hill descents a breeze.

Finally an update.... I went to the shop on Wednesday (yesterday) for a test drive. The transmission shop wanted me to drive my rig because they were feeling a vibration around 80mph. Sure enough, when I let off the gas around 80mph the truck sounded like something was binding up. I couldn't tell weather it was coming from the front or the rear? The tranny shop took abart the new front and rear diff and checked both my drive shafts. Everything looked just fine, so they are going to look at everything again tomorrow. However, if they don't find any problems they are goiing to put everything back together and I'm going to drive it around this weekend. With the new tranny, front, and rear diffs, the problem might just be that everything needs to simply "break" in. I just hope "break" doesn't become the oprative word. I'll keep you guys posted.....

Conrad II, any updates on your new transmission?
