Transmission HP Limit

    Anyone ever seen the HP limit of the transmission?

    Or heard of the transmission gears giving out?


    Wondering if I should stay away from sticky drag strips, with a 4th wheel limited slip diff/500whp/track clutch. ;)

    Is that a fancy way of saying your Sling goes fast? ...lol :00000436:

    Probably a valid concern. I played at the track one night. Made 3 passes with a best of 8:05 on a legal 1/8mi. 60' times were in the 1.8's and it slipped a couple notches on the belt. That was with 10lbs boost on a single rear tire.

    I can tell you from expreience that the synchronizers are tender. Mine has a gimpy 3rd gear synchronizer now. Don't affect up shifting but you have to burp the throttle down shifting. It's a pain in butt. Looking to buy another trans so I won't be down while I repair this one.

    Yeap, that has been the most common issue we have seen with the transmission dating all the way back to the Solstice/Sky, they basically have the same transmission in them. With those we would also see the 3rd/4th gear synchro issue that Ghost has. As for actual breaking apart failures, those have not been super common in the Solstice/Sky world with much heavier cars. Also, the AR5 transmission used in the Slingshot is used by a lot of guys as an upgrade in things like the Supra, just FYI.


    Hope that helps,
