I have a 09 Roush with the Tremec TR3650 transmission that does not want to shift into 2nd gear without a lot of force??? There is no noise or whinning coming from the transmission and the other gears shift great. The problem is when I do a normal or aggressive shift (3000-6000 RPM) I have to pull very hard to get the shifter into 2nd gear. If I pause or granny shift it drops into 2nd gear like butter. I should also note that downshifting to 2nd gear is never a problem it drops in without any extra effort or running through the gears with the car not running is not an issue. It acts like my first manual car I had back in the day where you could not shift into first gear unless you were stopped so I am thinking it may be the 1-2 synchro and/or a bent shift fork.
I have tried a variety of things from upgrading to an MGW shifter, replacing the fluid to Mobil1 and most recently Pennzoil Synchromesh. I also replaced the clutch line to SS per my discussion with Tremec but nothing has solved the problem. I am about to have my local Roush dealer drop the transmission to take a look but wanted some advice before I drop the cash because this will not be cheap no matter which direction I take.
