my rx7 trans is acting odd ,it's a 8 5 gsl-se = now have to hold the shifter in 5th gear or it pops out of gear,hit a bump,let off the gas and it jumps out of gear.+p till this it would grind a bit going 5th.5th gear is the only one I'm having trouble with.any help would be cool don

 

it sounds like a schorizer is out or something like that....best thing to do it take it to a good trans shop and let them look at it.
