Asking this question again for clarification. If one does not have an aftermarket drum and LBA, will launching car in 2nd avoid (for the most part) this issue? I suppose it would, but you generally need first gear in drag racing. Since it’s generally when you freewheel the trans in 1st without the band applied that the drum is at risk, Most do their burnout starting in second to avoid the issue.

Ascertain the performance required, select the trans and get out the credit card. There is no free lunch. They all have issues and their associated costs. I've been running the same trans since 1988, all Turbo Action parts including the valve body. No rebuilds just maintenance, 1.40 60ft times no trans brake. I'm just looking for the suppliers for the parts.

It's kind of funny a year ago I posted the question about using a turbo 400 behind my big block and was told to stick with the 727 even by Monty. GM Trannies explode too IF they are not built right or are abused. Any trans can be a time bomb if abused with the wrong parts. Th400 main problem is tossing into nuetral across the stripe. Unless you have a valve body deigned to do it. 123n. I currently run one. Easy to build. BOP versions are cheap and plentiful. Personally I have always hated the 2-3 shift on 727's and tweaking the band. The 2-3 shift is all about timing to avoid overlap and you can find the sweet spot by understanding the front clutch clearance, springs and the kickdown lever ratio and adjustment. The 4.2 lever is the best all around IMO, the rest comes from experience but a good 727 trans guy should know this.

Keith knows a thing or two about transmissions. Bought my aluminum drum from him as well as some other parts. I like Copes rmv bodies with rear band apply. I wonder about these new vb'd lba and if they were ever test on a bench or dyno to verify there correct function.[delay in shift 1 to 2 correctly.cause effect]

Are you meaning copes brand or that type VB overall? Any brand,The racers seem to be the test bed for a new product to work out the bug most of the time.

so why would anyone pay more for the super sprag if they break too? save your money and just install a bolt in stock type then and use an aftermarket drum. That's what I did.

Ironically one way to make a th400 bullet prof is to go sprag less which I think griner developed the vb for but...... The 2-3 shift becomes about timing to avoid overlap.

Did anyone ever check to see if ATI makes a 727 aftermarket case. My ATI Case is very heavy duty and comes with a steel safety liner that slides down into the pump

Ive an aa or aaa? I think cope uses his own now? And ive never noticed a delay at the track or street when hooked, if im horsing around and blow the drag radials off I can hear the 1-2 shift in the motor but its not enough to make the tach needle drop, by then im already in 2nd at 7200, about a second and a half but I always run it out when I do and it gently hooks, I never let off abruptly. Do the data loggers show the delay? I wonder about these new vb'd lba and if they were ever test on a bench or dyno to verify there correct function.[delay in shift 1 to 2 correctly.cause effect]
