Oil for Allison

I have a 06 Duramax, 130,000 miles and trying to get better fuel mileage. Going to do a tune, fix EGR, change converter on exhaust and add trans kit. I use amsoil in trans now and the guy doing the work would like to use super shift by amsoil and on amsoil website looks like ATL fluid would be better for my application. Not going race it or pull on a track just towing a 5000# trailer to jobsites. It was suggested to put on a 4" exhauts put not sure I would get a return of $600 on fuel savings and it would also be louder. Anybody have thoughts on oil and 4" exhaust?

Dex 6. Alot of guys run amsoil or transynd. Why 600? YOu can get a MBRP aluminized 4" exhaust for just under 300 bucks and your truck will run alot cooler.

600 for 4" SS. Does 4" do much for fuel mileage?

Randy, Transynd or Amsoil "Torque Drive" is the best choice for your Allison transmission's long term health and will reduce required maintenance.

Using Amsoil "Super Shift" is only recommended for a race trans or to salvage a slipping one. "Super Shift" doesn't have the friction modifiers of regular ATF thus causing clutches to grab MUCH harder.

The 4" exhaust will help some with fuel mileage but it's not going to be huge. Your EGTs will drop from the exhaust due to better flow, which is a good thing.

I use Torque Drive now but I see amsoil came out with ATL that replaces DexronVI. Was not sure if this was better for my truck.

Do you think the 4" exhaust would be worth putting on? They say it will be a little louder but I'm not sure how much. Don't want to hurt the resale and I put on about 30000 miles a year.

Allison TranSynd or Dex 3. I wouldn't run Dex 6 in anything.

Randy, The ATL(low vis) is fine and shifts slightly faster but the Torque Drive will protect a little better.

I have stainless 4" W/ Muffler, it's more of a daily driver friendly, non-teenager type setup.

Thanks for the info. I was wondering if the ATL would be a low vis for what I do. I'll stick with T-Drive

All the kids around here have 4 or 5" straight pipes. Little to loud for me pulling a trailer every day

Thanks Again

No problem.

Yes, most kids around here run straight pipes too, I didn't want that racket either so I went with a muffled setup.
