Corvette 2nd servo and the billet 4th servo how does this hold up without breaking th What about the Corvette 2nd servo and the billet 4th servo how does this hold up without breaking the band
i had dynotech preformance (in nj not there any more) build the second to last tranny that's in the car know and with both billet servos it snapped the band and had to have it replaced but the guy who did the work took out the billet set up and replaced it with the corvette servo which i find a big deference in the 3rd to 4th shift under boost to be a little sloppy it not slipping but i would like to have that snappy shift like before without breaking the band...
the specs fr the tranny when built by dynotech
"Includes Transgo shift kit, 13-vane blueprinted pump assembly,
Alto wide-band, Alto Red Devil 3-4 (alto wide band broke)
clutches, Modified lock-up controls. All new electronics. Teflon pump/drum
and tail housing bushings.
the Billet 1-2 apply servo, billet 4th gear apply was removed for the corvette servo set up

This tranny is in a lt1 car ... they used a billet servo set up but not sure from which company .... when the band broke the tranny guy who pulled it apart and rebuilt it throw out the billet one i had (which pissed me off)
So with the blower set up(I am making over 600 pounds of torque) I can tell the difference between top gear pulls with the corvette servo vs the servo i had in there before....... so I don't want a band problem again

The Corvette servo is a decent piece, it is large enough to handle significant power. IMO as much power as the trans design allows, so I rarely use a billet servo for 2nd gear.
You need to use an Alto band with reinfoced anchors and a billet anchor pin in the case to prevent failure in either case if you have it shifting hard.
Your builder may have "detuned" the orificing or accumulators for 2nd gear shift as well to prevent further band failures.
