All were computer controlled. I have one in my truck with the transgo full manual kit. Eliminated the need for a computer to control it. I put it in about 10 years ago when the electronics to run them were big money and i wanted a bullet proof overdrive. MSD makes a more affordable controller for it now. If i were to do it over again i'd go that route.

what about a 4l70e out of a trailblazer ss i have a guy with one that might want to trade some stuff. idk if it will hold 500 hp im thinking it will be ok since my s10 only weight 2800-3000 lbs and a trailblazer weighs like double.

Stock a 60/70 won't. Built right they will

Buy the 6.0 and 4l80e out of a pick up truck with the harness & computer.
Minimal changes to the 4l80e and a performance converter will get you where you need to be.
Keep in mind, if your buying a combination that has 150k on it, the trans will need to be gone through anyways.

What's a 4l80e normally cost to freshen up? Ballpark

i have the motor already and im having a harness made. im getting this 4l70e trans i found a rebuild kit for 400 bucks that includes a beast sun shell and alto red clutches and everything you need to make the trans hold power and i can do it myself. from what iv read the 4l70e trans is easier to fit in a s10 then a 4l80e so im running with it. i know this thing has to be able to handle power with the rebuild.

You may want to do a little more research in 4l60/70 parts before buying them. Beast sun shells have something like a 70% failure rate and Alto reds are not the clutch of choice for the direct.
My suggestion would be to study the products Sonnax offers. http://www.sonnax.com/landing_pages/gm_4l60e#builds
If you need help PM or email me any questions you have.

Rich. Have you used the smart tech input housing yet?

 

[DarkoStoj]

I have everything you need for a 4l80 swap. (built trans, converter, controller)

I put about 500 through my 60E behind mybheads and cam 6.0. I had over 70 1/4-mile passes all in the low 12s and high 11s at 4000-4100#. I recently put that trans into my stock wagon and it's going strong.

I'm a dealer for Sonnax products, so Ive used them since they came out, and use one in builds about every other week. I usually get a peek at products before they are released. The early ones did not come with a input shaft, so I was forced to buy them elsewhere and press them into the Smart Tech housings. Now they sell them with a upgraded input (I might add for less money than I paid for some input shafts). They also now make a billet overun piston, which allows you to use the factory steel molded pistons for fwd and 3-4.... somewhat confusing, but all in all constant improvements & upgrades. What has been released in the last month are output shafts.
