Good advise. I'm going to have my son try staging at a higher RPM.
Thanks, jim

Thanks, Jim

Just an honest question I hope u didn't take offense to. I have seen trans builders that dabled in the racing arena and it didn't workout.. sounds like you are in good hands.

No offense taken at all. A really good tranny guy is hard to find. The guy is a racer so he has experience. Stands behind his work and has a pretty quick turn around.

Thanks for the help Scott. I'll post how it goes with the diode patch.

Can you get the transmission fixed so it won't move? It shouldn't move when it's set.

Ok wasn't aware... so 12v to a switch then two 12V out, 1 direct to Tbrake, 1 to relay to line lock. Then wire line lock direct or with a relay as you prefer. All your trying to avoid is the 2nd line lock switch back feeding to the Tbrake or shorting - the switched relay does that.

So all can done with one simple 4 post relay you could cut out of a parts car or buy at any parts store. I have a similar deal with a lean out tied out to my Grid but also activated with my line lock. Gdlk!

Main thing with me is staging at same place each time..
Maybe lurch is responsible for my recent good RT's..
Good luck Jim...

My son was doing this quite a bit last season. He would stage the car and leave his foot on the brake. When he went throttle down the car would lurch a bit, then he'd red light. Make sure your foot is off the brake after engaging the transbrake so the trans can set. If the transbrake is working correct you don't need the line lock.

After I got the hang of it and how much it would move...I used the button to bump in beam once pre-staged.....May not be right but it seemed to work out..
Going to try raising RPM's next season...

Troy: Take a look at my thread on YB. I got the diode patch made by Shawn at G.A.S. racing. Very easy to install. Haven't tested it at the strip yet but my test light tells me that the transbrake and line-lock come on at the same time when setting the transbrake. And the line-lock can be operated by itself for burnouts. For $25 delivered I think it is worth a try.

For anyone interested: My son and I took the Catalina out to test the diode patch.
Went to an abandoned parking lot nearby. Rob "staged" the Catalina as he always does.
He came up on the TB, released foot brake, brought up the RPMs and the car didn't move in the slightest. Tried it several times with the same success.
