I will be installing a Corvette servo and Transgo in my 4L65E VHO. Is it possible to configure the Transgo/PCM to get slightly firmer than stock shifts at part throttle, then make the tires bark under WOT? If it is possbile, can someone give a quick outline of how it is done?

Thanks

 

I got mine to shift harder at part throttle and barely bark 1-2 at wot
by corvette servo, leave 1-2 undrilled drill 2-3 .082 and the rest .093
keep stock spring in accumulator "dont use the blue or orange"
no washers and i didnt change out the purple spring
I also replaced the 2 plastic accumulators with pinless sonnax bits
and removed all tm

 

If you want the tires to bark second at WOT only then I would use one washer in the 1-2 accum. Thats what I have mine at and at say 1/3 throttle it is fir mer than stock but not reall that much. Also if you do the Transgo your tranny line pressure has to be where it was stock. So if you have a custom tune already you need to get your line pressure put back to stock also your gonna want to remove some torque management. I would say remove at least 60%-I removed 100%

 

Can I lower my line pressure to less than stock at part throttle, and get softer shifts? I would like to use 2 washers, drill the holes fairly large, and install all the stuff from the kit along with the Corvette servo. Then in HP Tuners, set the line pressure at part throttle extremely low so it would shift close to normal. Then adjust the curve to stock pressure above 1/2 throttle.

Does anyone know if this is possible, or would work?

 

Try Allen, he should know something about this. If he cant help you, try Geoff at Thunder Racing. I think I recall someone one this board making the line pressure progressive. As in: less pressure at part throttle, high pressure at WOT. Also try some of the guys really familar with edit. (Parish8, bigtex) they are bound to know what parameters to go into.
