Trans Problems!

[ss3011]

Some of the aftermarket high gear drums have sprags that do not have end bearings . These are no good , the end bearings keep the inner and outer races concentric . Without the end bearings the sprag dog bones will not engage evenly and will roll over in short order .

[Mike Pearson]

one reason I stick with a powerglide. They are virtually indestructible. Not as fast as a good 3 speed. But very consistent and reliable. I know I could pick up a couple of tenths with a good 3 speed like a Coan XLT or a Pro trans.

Another thing. Be sure the trans builder did not remove the accumulator spring. Some do. It will make the shift into second very harsh, which is hard on the intermediate sprag.

[Larry Hill]

Do the water box stuff in second, it keeps wheel speed down and doesn't abrad away the center of the tread. Transmissions and tires will last longer.

Do NOT end your burnout in second gear, if it hooks at the end of the burnout in second gear, it's almost guaranteed to roll the sprague. Always finish your burnout in high gear.

We always do the burnout 2-3, but we've always hit neutral at the finish line and shut it off.

We did that for years with our Glide, but now the TH350 can't handle it I am guessing. Thanks for the input guys

I've been doing high gear only burnouts with glides and 3 speeds (T400, T350, and T200) for years. Currently have a T350 in my Super Stocker. Never have had an issue with any trans that was burnout related. I was told years ago by a reputable trans builder that one of the hardest things on a trans is shifting in the burnout. As long as you have some dampness on the tires, there is no need to be in a lower gear for the burnout.

I too neutral the car after the finish line. My current trans builder hasn't yelled at me yet for doing so... :-)

And, my Pro Trans (T350) has the “Clean Neutral” option. Shift to Neutral at the finish line, with no issues.
