I'd give Shep a call tommorrow.

Sorry ,no used forks available at this time. You may want to give Dodson a ring.

 

[alphan]

he already knows.he was searching

Has anyone ever broken a shift fork on a transmission with factory gears in it?

 

[heacuva]

yes, the op did

 

[Martin Donnon]

yes, the op did

Not so sure about this one heacuva....
Check out a stock first gear GTR transmission -

Now check out the first gear in the OPs transmission. Doesnt look like a stock gear to me.

 

[alphan]

first gear is ppg

 

[heacuva]

the op is sneaky, never told me he bought the ppg 1st gear set

I would be having a look at the setup of the transmission build and have a look at why selector travel may be now reduced over factory. This is why when we limit selector travel with WR35GS we do it at the shift piston, rather than having the lever moment of braking the selector come back through its cast body. As for the selector we have this part drawn on CAD, its a matter of whether you want to commission us to machine a billet piece for you. Regardless of who/what shift selector you use to repair the transmission, address the problem of the selector over travelling to prevent further carnage.

thank you forged performance workers.my car is on the way again by the help of you. thank you

 

[Martin Donnon]

Now make sure you dont overtravel the selector and break it again.....it broke for a reason in the first place

 

[alphan]

Can it be because of 800hp clutch pack. Because it stalls when you slow the vehicle and when moving from standing still the car wants speed but when you are in a traffic jam you cant move at an idle speed. The car stalls at speeds 5-10kmh

Every broken selector issue we have come across is due to an incorrect clearance in the transmission. The selectors arent particularly strong, and having them hammer into the synchro dog stop constantly will eventually cause this kind of failure. The way it works is that the TCM signals the transmission electronics which move the hydraulic pistons, which actuate the top of the selector (where this one broke) which them forces the shift and slams up against the synchro dog stopper. This is why we limit the movement of the hydraulic piston right back at the source of the shift so that big shock loadings arent going back through selector arrangement. 'Short Shifter' designers for manual transmissions have been doing this for years - limit the travel - and save the selector assembly from 'overselection'

Regardless there is something terribly wrong with your clutch setup, what type is it?

Hey, since this weekend, i got the same problem on my GT-R.

The Gear Selector Fork for Read and 1st Gear broke down. :-(
Got Dodson 1st Gear with circlips and GTC Clutch.

Can someone offer me a gear selector fork?
Is there any introduction how to install it?
Any special tools needed?
