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.

no no. the feeling that the trans actually locks in the gear. here try this, unhook the shifter cables inside the engine bay, have someone play around with the stick, by putting it in all gears. look and the cables if there is enough movement like 3/4in to 1in (dunno if thats too long). look for movement, i guess you have to use your judgement if its enought to pull and push the actual part that's selecting the gears.

IIRC but pushing the lever towards the trans mount is 2nd and pushing it towards the intake manifold is 1st. Before you do that have someone shift into all gears and see how the arms and cables move.
