Hello,
i have ''grgrgrgr'' type of noise coming from gearbox when floor it at around 1800rpm and below. Most significan in 3th, 4th and 5th gear. Noise stops above 2000rpm. Gears are not grinding, shifts well. No matter if it is cold or warmed up...This started a couple of months after i've installed JUN SMF 6.3kg, leaved OE clutch in it. Transmission has fresh 75w-90 oil in it.
Anyone had this problem before ???
