DIY: Lockup Switch install into Gear Selector Arm

[Russ Roth]

The lock up switch works great with an exhaust brake, but I advise you should have s billet flexplate and input shaft. Not having them is risking serious damage to the transmission pump and torque converter.

 

 

While I only had an untapped comp and a Dunrite VB I ran mine with stock trans for at least 6 years and had no issues in that time including shifting locked towing.  Did not have it with stock VB so that may be different.

Nice write up! Once I get my PCM flashed (my truck's build date is 11/95) I'll be installing a lockup switch.

I would highly recommend a momentary switch for the lockup.  It is VERY nice to have it only lockup when your pushing the button.  

Even though I would love to automate 2nd gear lockup, and I am actively working on it,  I can manually shift 1-4 controlling lockup in 2-4 without issues.  2nd locked is a monster.

A momentary switch is definitely the way to go. I too would love to automate it, if I had the money I would try one of the aftermarket PCMs. I wish my VB was set up for 2nd gear lockup, I need to see what needs to be done so it will.
