Default Trans-Brake on a 4L80E or 4L60E????

I know a trans-brake is engaging first gear and reverse at the same time to "lock" the transmission. On these electronically controlled tranny, can you just hot-wire the two solenoids to get this effect. I know there are other mods need to make it all work. So what do you guys have to say?

The solenoids only work for foward gears in combination for shifiting only.

Reverse is mechanical. Low-reverse friction & reverse input drum make reverse all solenoids are off except pressure solenoid.

I have seen that Yank makes one for the 4L60E. Who make the unit for the 4L80E?

The "Pro Yank" transmission can withstand up to 700 lb. ft. of torque! (compared to 450 lb. ft. stock)

The Yank "Sportsman Pro" transmission can handle up to 600 lb. ft. of torque

All 4L60E transmissions have extra clutches and exotic materials for maximum holding power while using "power adders".

The "Pro Yank" transmissions will shorten shift cycle time in half. This will decrease ET by at least 1 tenth!

Trans-brake applications are available, however an appropriately beefy rear end is recommended!

SLP/Yank Sportsman Pro 4L60E transmission: '98-02 4.8, 5.3, 5.7, 6.0L LS-1 $1,850 For photo, press

Rossler is the only one that has made a 4l80 with a trans brake and he has only made 1 of them. Been trying to get him to install one in my 4l60. He say's he will but I have to wait untill winter when its slow for him.
