$200 for the TCM itself plus shipping (Standard Shift points, NOT the towing tune)

I bought a used TCM to swap back in. This would work great with 4.10 gears and larger tires, but I am holding off on gears for a while

I might be interested, I guess I now know where the TCM I was going to buy just went.

I was just going to have it gde fuel economy tuned anyway!

I have the TCM tune, and I would think it improves your fuel mileage, plus gives you the full torque that Chrysler robbed from us during F37. I am keeping mine. :frankie:

Locks me up at less than 1500 rpm which bogs me down. Great tune but I need to regear to make use of it with my 32" tires

I just got a line on some 32" tires myself...not sure if I'm going to do it yet, but they're really tempting. I'll let you know if I want to get your TCM when I finally decide on the tires. How much lift did you need to run the 32's?

what's the deference from the gde tune and a non Chrysler molested tmc? I have one and always wondered. My last lock up is at 59 60mph.

Doc444 quoted below: (from viewtopic.php?f=5&t=69663&hilit=gde+tcm+tune+shift+points)

1. If operating properly, ALL GDE TCM tunes, at below 3/4 throttle acceleration, lock the TC at 35 MPH.
The TC continues to STAY locked as long as you do NOT exceed 5/8-3/4 throttle OR you hit the OD button.
The "regular" TCM tune shifts to 4rth at around 46 and 5th at around 58,
The "standard" "Tow Tune" (custom shift points are available) is the same, except the shift to 4rth is delayed to 70.
It will then hold 5th down to around 55. After getting into 5th and then slowing down, you can regain 4rth by hitting
the OD button momentarily and shifting to third, then hitting it again to go to 4rth.
BOTH TCM tunes add 2-3 MPG in the speed range of 35-55 MPH. Above and below that range, there is no difference.
The "tow tune" is essential if you are towing over 3000 lbs in hilly highway terrain,

2. TC "shudder" is usually only an issue at the shift to 5th at 58 MPH.
The "original" ECO tune cleverly reduced torque only during this event. Once the TC has locked in 5th and this speed is exceeded,
the full torque of this tune is available and does not create a problem unless your F37 converter is really bad.
The "full torque" ECO eliminates this feature and may make slightly better fuel mileage than the HOT, which is my preference.
You can get great mileage with a light foot with the HOT and if you are towing heavy, it is the ONLY way to go.

I chassis dyno tested (see my old posts) the original GDE tunes as they were released against InMotion SII back in 2007-2008
and had the privilege of trying out the various prototype TCM tunes as they were developed.

If you have not installed a TC with upgraded springs ("euro" or a very recent Suncoast with "euro" springs), you should only get
the "original" ECO tune. This will save both your TC and, ultimately, your transmission.

Upgrading later to a higher power tune when you replace your TC only costs a few dollars. Keeping the material out that gets
dumped into your fluid when your TC "shudders" is critical. You should alter your driving style to eliminate "shudder".

I've been running wheels/tire off of the JK Wranglers Rubicons. The OME springs work great to fit the tires!

Man,

I really gotta take you up on that offer to check out your ride! Next time I'm on Oahu, I'll give you advance notice and hopefully I can check out the lift and tires. They look great!

What kind of fuel economy do you get with the lift and bigger tires? That might be the biggest roadblock for me.

Thanks,

Jon (Used to be Groelzj, now JieselDeep)

Between 20-25 almost all city. I can easily see 30 still on flat highway
