Anyone Experience this??, Manual Tranny Shifting Problem Options

[Fastbird]

This is probably going to be for the forced induction guys more than anyone, but here's my issue:

I CANNOT hit a hard shift into 2nd at WOT in the car. Simply put, the tranny refuses to go into 2nd gear, and third gear offers quite a bit of resistance at high throttle inputs also. When driving easily however, it shifts fine into any gear I want it to.

Call me crazy but I've always had trouble shifting cable actuated manual transmission under heavy loads. What I think is happening is that my old/weak motor mounts are allowing enough movement in the motor that enough of a shift happens to throw off the sync of the cables to the shifter. What I'm trying to do is get some verification on this.

Thoughts? I must have tried 4-5 times last night on the way home from work to bang a high RPM WOT 1-2 shift and it wouldn't happen.

i know what you mean. yeah mines is unsheathed about 2in's also. the cable on the bell crank bracket only justifies the left to right movement of the shifter. at one time my bushings wore out and i could shake the shifter left to right while its in gear. pretty scary when driving too

changed the whole bracket and bushings and its all good there. my cables got shipped and should be here. i looked under herosblade's car while doing his axle change. it seems all too easy to change the cables. i'll let you know Piro if that doesnt fix.

im pretty confident though that it will, if your synchros are bad you wont be able to put it in gear when its off or on.

ah! my shifter is VERY loose when not in gear i can move it left and right easily!

and BTW... i forgot to mention that i can shift that $#!T into gear without the clutch when the car was off!! i didnt realize that!!!

and thanks 808, can you take a pic of where u changed the bushings at and the bell crank bracket?

hate to burst your bubble but everyone can do that... the flywheel and input shaft are not turning so as long as the gears are lined up you can shift into gear while the car is off W/O the clutch... so you might be able to shft into a few of the gears when the car is off... depends how far they have turned since you shut the car off pushing the clutch allows the input shaft to turn... allowing you to push it into any gear that might not be lined up...

but the fact that your gear problems are all on the bottom gears means something important... its not clutch, its not synchros... your list is as follows... shifter bushings, shift linkage bushings, shifter arms, linkage... it HAS to be one of these... good luck to you!

This was my point also - Happy hunting guys
