Exploding Torqueflites

Very good article, Chris. I have a Cheetah manual valve body in my 727. Don't know if it has the low band apply or not. I read somewhere that it alot safer to start your burnout in 2nd gear and then throw 3rd, and that's what I've always done. Does this alleviate the potential for disaster? Thanks.

Hi Dan,

I am positive that your turbo action reverse manual valve body is not applying the L/R band in 1st. However, you're doing everything right as far as your burnout goes; start in 2nd and shift to 3rd.

You would still practice the same burn out technique with a valve body that is applying the L/R band in 1st. The low band apply valve body will decrease your chance of having a sprag failure and possible transmission explosion.

With the valve bodies that aren't applying the L/R band in 1st, the sprag is very venerable, presenting a greater chance of damaging the sprag because the low/reverse band and drum are not "cushioning" the sprag.
