Where did I state that “they just throw them away”?

I’m trying to get the point across that these are dependable and durable autos. There is plenty of documentation here about how many use it with the cable just tied up and wide open. Rory (RAD Designs) will also suggest you do in your application, he did on mine.

If you are hell bent on using the kick down cable you may just have to figure it out yourself, I don’t know anyone who does in this application.
Quoted for truth. One of the most durable transmissions ever built.

I run mine with the TV cable pulled tight, shift kit with the largest opening, and a 2800 stall. Sucker gets hot in some racing conditions, but it keeps going.

Beware, pulling the cable tight has been known to cause overheating issues. Transgo kit is a must.
I followed your advice and installed a Transgo kit. I will say though, if I leave my aftermarket cooler and fan on I can be hard pressed to get tranny temps up to 180*.

Thanks for all your help during my build, I have been pleased with this choice in my crawler and your product has worked flawlessly for me so far.:smokin:

Thanks for the feedback.
I have a customer in WA that had trans heating issues until he connected it to function. It doesn't seem to be every trans that does this I agree. Just something to be aware of.

I'd be interested in seeing if hooking the TV cable back up to the TB, makes a noticeable difference on trans temp.

I run mine pulled tight. I have no temp issues when crawling or trail riding. I just did the Rubicon end-to-end in one shot and it never got over 175 degrees.

When racing in Mexico, I got that thing past 250 degrees. Where it got hot was when loaded up going through silt, sand, and steep rocky hill climbs. I was looking for every opportunity to get to areas where I could get above 4000 rpm for 30 seconds plus to bring the trans temp down. In the 4 miles of whoops, I could bring the trans temp down nearly 30 degrees.

I'm sure the high stall is a huge contributing factor, but its weird how the high trans temps are associated to a specific terrain: high load terrain where high rpms cannot be sustained or going slow is not an option (racing).

One thing I thought about was wiring up the TC lock-up to help combat high temps. I could manually lock up the TC when not under load, to help bring the temps down further. I just don't want to forget about turning the lock-up off. I thought about wiring the lock up to an RPM activated switch but I am nervous about engaging the lock-up at 75% to WOT.

I wired my TC lock up to a switch and have a light to remind me its on. I do believe having the ability to lock it will help when racing. A couple customers I have talk with have commented that's the setup they use.

I literally said it may cause issues. Not sure how you got hell bent out of that.

This is the "Issue" I was talking about.

I'm going to say that this can be put to bed. I ran a pre-run lap last weekend at the Ultra4 race with the cable accidentally disconnected (not pulled tight), trans temp got up to 210*F.
I reconnected the cable so that it was always pulled tight. Ran the race (giving them LS boys a run for their money), and the trans only got to 210*F. This was the hardest we ever pushed the car in 3 years of racing.

I will say that the trans took longer (30 miles versus 15 miles) to get to 210*F during the pre-run with the cable loose, but we were not driving the car nearly as hard.

IMHO don't think the cable being pulled tight necessarily increases the trans temp.

I did this and I did not see a noticeable difference with the TC locked up. I played with it while pre-running, but didn't use it during the race. Maybe I was expecting dramatic results, and that may have been an unrealistic expectation on my part. I also found it difficult to run with the TC locked as it somewhat bogged down the motor on anything other than long straight aways (which were far and few between), and made it had to stay at a competitive speed. The desert out at Ridgcrest was the roughest desert we raced in so far, so this may not have been the best way to see what kind of improvement the TC lock-up could do for temp management.
