I have a 1999 LT with around 40,000. When she is hot down shifts are a little tough. I usually end up blipping the throttle to help the shift. The clutch has no slippage. I changed the clutch oil and all of the shift linkage with no improvement. Today I removed the drive and the clutch slave unit. There is no evidence of the slave leaking. The pushrod ends look great with minimal wear. I am going ahead and replacing the slave but I was hoping for suggestions as I was expecting to find a failed slave cylinder.
