$18K Repair on 2010 Burb? Yup, it made sense.

[fozzi58]

Thinking out loud, am I better off getting a used L86 (6.2L) when I am ready for a rebuild, rebuilding my 5.3, or just going straight to Hawks for an LT1 drivetrain?

The 6.2 is obviously going to provide more power but I need to acquire one I'm thinking the cost to get one will probably offset the cost to beef up the 5.3 since its in the truck already. (Yes I know, the 6L80 will need its own beefing up)

I did see some decent pricing on LT1 drivetrains at Hawks. Not sure I want my daily to have a 6 speed manual either (although I have seen a few conversions) cause none of the LT1s for sale come with the 10 speed.

I can't even imagine the cost of an Esky V drivetrain would cost.

Makes me hope I can save up enough to have my 2010 2500 turned into a Duraburb if / when it gets to that point.

Best to contact DuraBurb now so you can get the shopping list. You always run into the perfect, inexpensive motor or trans exactly when you’re not looking for it.

It’d be nice to drop off the truck for the conversion and have the drivetrain costs already covered knowing you got a good shake on the pricing.

what are you trying to do? swap in a direct injection LT manual trans to your tahoe?

I’m sure GM is reading that article and hoping it gets mothballed.

Ever since they switched from global architecture A to B, no modules on these trucks are cross compatible after 2015 without some major software hacking.

I’m following this upgrade from 4/6 Speed to 8/10 speed trans carefully.

10l90 swap into a l83 w/6l80e?

Like the title states, can you swap a 10l90e into a 18' sierra 1500 4x4 with a 6l80e? Thank's yall!

Not sure if you have seen this company or not but they are offering 10 speed swaps into a lot of different platforms now. From the videos I have seen they seem to work pretty much like factory. I am hoping at some point to do the same to my truck as the 10 speed is so much better than the 6 speed in almost every way.

I'm curious, I don't know much about autos. what makes the 10 speed much better than the 6 or 8?

from what I've seen online all the new transmissions need replaced every 100k or so miles of normal use?

I've heard it shifts faster and smoother. Keep you in powerband better.
If you watch some videos, it definately sounds like a faster shift..

IMO the 10 speed has much better splits between the gears so there aren't the kind of "dead zones" where its too low of an rpm to really accelerate as needed but too high of an rpm to downshift. I had the 10 speed in my mustang a couple years ago and it just always seemed to have the right gear for the situation. Kinda like the transmission version of a well broken in pair of jeans or shoes lol. Also, the shifting can be pretty buttery smooth while driving around normally and lightning quick when wide open, and again, always in the right powerband sorta like a properly sized aftermarket torque converter without the soggy, terrible shift those create.

As far as the life expectancy, I think with proper maintenance they will last much longer. I think a lot either abuse them constantly and/or don't take care of them.

*EDIT*I think long term, swapping a 10 speed in and keeping the LS is the right move because of the long term LT issues with valve coking and stuff. Plus, for some reason GM made the LT engines harder to work on. The way the front cover and oil pan seal together means you have to drop the pan more or entirely for cam swaps for example. I think a properly DOD deleted gen 4 LS is the sweet spot for many thousands of miles of service and TONS of aftermarket replacement parts to keep it going.

see to my ear that just doesn't sound faster, all I hear is a bunch of shifts. tq reduction between gears would mean it's always limiting itself. unless you zero all that out which is ******* everything.


it's like at some point, especially in a turbo application, going from a th400 with 3 years wasting power to 2 speed glide is faster.


I know we aren't drag racing, just putting around town at part throttle. but a ls has a nice wide powerband compared to say a coyote that makes power way up top.


I mean I'm all for it on the side of its cool to get a old ecm to control a new tranny. I'm just not sure for a daily it would be totally worth it. the 6 seems pretty good
