badass billet piece!
installed this piece in my 05 crew cab silverado and it shifts firm not too aggressive in my opinion. i want to thank the global transmission support team for helping me with the inconveniences i encountered (all was user error) but got it all sorted out thanks to the help of the global transmissions team.

Super Servo
Awesome product. This Servo along with the TransGo HD2 Shift Kit gives many options for how and when one can program the the transmission to shift and how hard to shift. Very satisfied with this product and would recommend this product and Gobal to anyone that wants and needs professional products and service.

Shifts Hard!
I bought this servo for my stock 84 305 Trans Am and I love it! It shifts super hard at wide open throttle and super smooth at a part throttle cruise. It barks 2nd gear now which really surprised me for an all stock 305 and it is definitely putting more power to the ground too. Even though I had to undo my transmission crossmember and lower the trans. on a jack it was still easier to install than a shift kit or valve body and much more affordable too. Here's a link to a video driving with the servo in my car. https://www.youtube.com/watch?v=lgNGsq_65tQ
