GT Transmission/3.73 rear
I'm toying with the idea of getting a FRPP Pumpkin at some point when I have the money... The problem is I have a '99 GT transmission in my Cougar. I know there are no gears that wor *reliably* with the 8 tooth OP shaft, and I would rather not go the way of a speedcal (want to keep it clean). That said, it would mean I would have to tear down the transmission to replace tho OP shaft.
I just skimmed through Trans 101, and found that the older (95) OP shafts where made of a weaker material than the 98+ ones, so I shouldn't use the OP shaft from my 95 tranmssion. What else should I do while in there (I've done the JMod)? This transmission could end up behind a 450hp DOHC 4.6 (maybe), so I would want to build it to handle that, possibly build extra in...
I'm guessing the following:
-New 7 tooth OP Shaft
-5.4L Panetary Carrier
-Forward Sun Gear
-7 direct clutch plates
-6 forward clutch plates
-Wave plate for SC (5.4?)
-HP intermediate clutch friction (if I drill to the >450 for the intermediate)
-2.7" OD Servo
-5.4L EPC Solenoid
Am I on the right track? Any other words of wisdom?
