I have a 95 Sierra K1500 with a 5 speed manual, that has developed an issue when shifting between gears. For years I have delt with the known issue of difficulty shifting into 1st and Rev. without first putting it in 2nd or 4th, but this is different and getting worse. I seem to have almost no play at the end of the clutch travel, ie when in gear I only need to let out a fraction of an inch on the peddle before I feel it start to engage. If I have trouble putting it in gear and I pump the clutch several times it seems to work better, but recently that is having less positive effect. I bled the clutch and did remove a tiny bit of air, but though this helped a bit at first it did not seem to last. The clutch parts, master cylinder and slave were replaced about 50K ago. One thing I did notice and am really wondering about is the position of the slave cylinder. When bleeding I thought it was weird that the bleeder valve is on the bottom of the slave (6 o'clock) and not the top (12 o'clock). It would seem that this 6 o'clock position would not let all the air out of the line. Could the shop have installed this upside down ?? I could easily remove the two bolts on the slave and rotate it 180 degrees putting the bleed valve on top. The other strange thing is that this entire issue seems to be getting worse the hotter the outside temp. It also shifts better when I first start out after the truck has been sitting for a while, and gets worse the longer I drive it.
Any help would be greatly appreciated, James
