my '94 z28 with 6-speed has twice gotten so sticky, i thought the tranny was going. Like stirring molasses! the 1st time it was after 3 hard-shifting runs at the track. after 15 minutes, it magically went away.

the last time was this week. i had to valet park it (which i almost never do) and when i got the car back, the stickiness was there. this time it took over 24 hours to return to normal. and it did, smooth shifting as ever.

has anyone had this before? it just made 50,000 miles and i've made an appt. on may 24 to have the tranny and diff. fluid change.

also thinking of replacing it. Is the Hurst shifter good?

Any possibility the clutch is getting fried? Dragging clutch will do this. Also might look at hydraulic clutch fluid contamination. Probably not, but you never know.

zzsurf88,
Are you still running the factory fluid in the trans? My understanding is that these transmissions came from the general filled with auto tranny fluid.. Yuk! I have a 69 Camaro that I have retrofitted the T56 into. One of the first things that I did was to drain all the auto tranny fluid out and replace it with (4 qts) of 5W-50 synthetic engine oil. Several different tranny shops I talked to advised me to do this in addition to the local racer scene who are running this trans. I can tell you that it is as smooth as a babys bottom when it comes to shifting and I have had no problems with it.. This might be something you want to try before laying out some big bucks on a new shifter or clutch/pressure plate assembly.
