Started with a vibration on clutch bite (thought it mybe thrust bearing), then trouble selecting 1st & reverse (but had same problem with all my jap cars). Now having trouble selecting some gears, clutch seems to slip into 4th when under boost but seems ok in other gears, Also strong smell of burning, and a rattle when driving at at low rmp.
Have no sign of leaks
Oil levels ok
Tested the clutch pulling away on a hill in 2nd and did'nt slip
ANY IDEAS (wondered if oil mybe getting on clutch)
