Unless you treat the gears (shot peening, cryo, wpc, whatever) you are not increasing the strength of the metal. The REM reduces friction from what I understand, and does not increase strength. While "built" 5 speeds may handle higher loads better, they are still using OEM gears and Shep (from what I know) is not a fan of shot peening or cryo.

This Shep 6 speed will actually be built with stronger gears for 3, 4 and 5.

If the 6 speed already has wider 1 through 3 gears, wouldn't it make more sense to strengthen 4, 5 and 6 instead of 3, 4 and 5? I like cruising in 6th and putting the pedal to the metal so to speak!!!!

I think Shepard's goal was to increase the strength of the gears that will receive the most abuse racing....3, 4 & 5. Also, the new FD lengthens the gears and kind of addresses the issue. 6th gear is a cruising gear, not a racing gear

If it's not a problem in the 5 speed, why would it be an issue in the 6th speed?

Ever since I bought my car new shifting first to second was really tricky. Half of the time it felt like it grinded a tiny bit engaging into second unless I either

1 - really babied it at low rpm

or

2 - was driving rather agressive and let it rev past 3k before shifting to 2nd

Just being normally gentle and shifting into second around 2K was/is tricky. Been this way for 18K miles.

Don't have any experience with the AMSoil stuff. I had no reason to use anything else after the Castrol solved my grinding/notchiness problem.

Here is more info on it if you're interested:

I don't want to get I to a pissing match with Mr. Amsoil on here again but when I when from royal purple to Amsoil my 4th gear started grinding at high rpm up & down shifts...I hated it...I have BG fluid in there now & almost no grinding at all...much smoother...

I've been talking to shep for the past 2 years about this... 90% of what you guys mention about his test cars, power figures, runaway tester that sold his car, etc... are true

Subscribed.

It's only a short matter of time before it comes out. Last news I heard from him was that 25 are being mass produced at the moment and pricing will be released. Currently I think he's on vacation. As for a date, I have no idea. I'll keep everyone informed. I expect the same if anyone knows anything new.
