Hey guys, I found this items on OPT and they seem to do a good job for my tranny.. what ya'll think of this items?? would I need a retune from Allen in case I decide to install this things???

SONNAX 700R4 4L60E SERVO RELEASE CHECK VALVE

SONNAX 700R4 4L60E 4TH GEAR BILLET SERVO

SONNAX 4L60E TCC APPLY VALVE

SONNAX 4L60E REVERSE BOOST VALVE & SLEEVE (.490")

SONNAX 700R4, 200-4R PINLESS 3-4 ACCUMULATOR PISTON

Also looking forward for a tranny cooler.. (40,000)

Thanks!

no help?

I would say no on the billet servo because they put a little to much pressure on stuff but other wize it looks good and yeah u would want to let Allen know about it
