In the diode drawing example that I posted above, you see a TB lockout relay that is use with my th400. The ecu activates this relay anytime the car is moving faster than 1 mph removing the +12v to the TB button. Having TB button mounted on the steering wheel this relay has avoided unwanted TB activation.

I just don't roll in N or 1st anymore. Problem solved.

Is that if your racing a car that weighs what a dumptruck weighs? LOL I have abused my glide for years and never had anything go bad. I'm only 1990lbs though.

Yeah, I'm 3250#, just a little over what the OP estimated for weight.

It took me 2 pukeglitches to get through about 1/2 a season, and ruined a couple of T-shirts.

Dirtyback transmission is what I call 'em.

Dave, I don’t post misinformation .
I’m not Ed!
We’ve had 4 of the best 400 in the country. I have years of data to back my claims and my partner will attest. The glide stays put when the brake is applied every time. Glide feeds different. 400 doesn’t do it every time but it will bite you in a late round. Not just us but every fast car we see here did the same thing. The fix was as Mark posted. Wire through delay box to the line lock. The only thing we came up with is the 400 feeds totally opposite of the glide and bigger cavities.

I posted info on what we found and the fix. My opinion, I hate the 400. Besides costs It cost us at least two to three wins and probably a third championship.[/QUOTE]

I don't doubt that you have had problems, but if you think your 400's were "best in the country", you're simply delusional.

Now let's discuss pinion angle.

Mine uses 1+2 and rarely in high gear off the racing surface
