9K just to harden it...

I was on the dyno myself so these results are true and not a dream from alot of tuners which state 700 and dont get it. There are not much who knows how to tune gearbox beyond 1000nm. i can fully recommend the tuner.

Weistec bulletproof transmission. You can get there in House upgrade or you can order their clutch packs. If you send your transmission to them they will cryogenically harden a lot of the components. This is a dubious science, it may benefit the transmission it may not.

when I sent them my transmission that took a lot longer than they said they would and stopped responding to my emails. Whenever they did respond it was always to say there were two weeks left. I think they didn't realize that they said this already months before and I suspect this a generic reply. Same when I sent them my turbos I was told 2 weeks and it took four months despite emails and phone calls from me asking them how much longer. The reply was always 2 weeks.

Many of their customers are happy with their transmission although some have reported issues with clutches slipping. I had mine inspected when it was brand new and was told it was a definite upgrade in terms of torque capacity. Their clutch material will result in harsh shifts.

Gad motors upgrades more than just a clutch packs. They don't do cryogenic stuff that actually replace other components as well and can hold 1500nm. Also the clutch engagement is more gentle similar to stock because of different clutch material and different clutch design.

they required two days to do the upgrade much much faster than weistec. Let's see the WeisTec transmission fails and you want to send it in for a service as it has happened with other customers you'll be waiting for several months vs 2 days if you ever had to resend your transmission to gad Motors.

I paid over $6,000 for weistec exhaust and it did not fit due to poor quality control so I decided I couldn't trust them with my transmission and even though it was brand new I had it rebuilt at Gad Motors for peace of mind. So all that waiting for weistec transmission and the $6,000 it cost all in the garbage for me. I could have given their transmission a chance to prove itself but when I saw that their exhaust didn't fit for my car and for another one of their customers in Edmonton I but the bullet and went with gad.

if you don't want to spend that kind of money you can get the clutch packs from weistec, AMS or renntec. You could probably send your transmission to AMS and rentec is well and let them do the build. They will upgrade most likely the clutch packs only but you will save money that way
