    Thumbs up The "Look"... Update 2/5/2024

    I watched a couple of pickup truck related events on Youtube recently. The first photo here was screenshot from the 2023 Hot Rod Powertour video while the tour was in eastern Tennessee and the other was from a video about a Chevy C10 group event that was sponsored by LMC Trucks. I saw a couple of trucks while watching the videos that made me hit the rewind button....





    Though Lil Red is now 35 years old (but 20 years in its present form), it seems some of the design elements may have appealed to a couple of other truck builders. I think its cool.

    Post Update - 2/28/2024 - Purple Power!



    The power increases eventually reached the limits of the factory Allison. In working with Kennedy and ATS, we came to the conclusion that the "ATS Extreme" Allison would be a step in the right direction. It has been. While the original factory Allison could be made to slip with 500-hp and a power-brake launch at the strip, the ATS has yet to slip, even with more than 600 hp. The torque converter contains a 5-disk pack that provides for a solid connection once locked.



    A local friend who also just happens to own a mechanics garage (and is a transmission expert), worked with me to install the new ATS Allison. The lift makes this sort of thing so easy, when compared to a transmission floor jack and jack stands...

    Shift quality while using performance programming was pretty "performance oriented", sometimes producing a little "bark" from the rear tires at gear changes while on local highways. Who can resist using a little pedal? But, when toning down the ECM programming to near stock levels, the ATS Allison gets real close to factory Allison shift quality.

    I've not had any code setting with this transmission - or any other problem. There's only about 12K miles on it since installation, and the ATF fluid remains nice. The transmission has seen only a couple of dozen 1/4-mile runs and a similar number of dyno runs so far, plus highway driving. But, I do plan to service the transmission this coming spring - new spin-on filter and pan filter, plus a fluid drain/refill. I'll report back once that's been completed... if we find anything unusual. Jim

    Are you running Kennedy's tune on your truck? Or a custom version of his?

    Currently, the truck has a Kennedy switch-selectable tune - a stock power setting with fuel economy, and a +100 hp setting. Time flies, but this programming was added not all that long ago. Jim

    How street-able is the 100 hp setting?
