So I had a new RPC Stage 2 clutch fitted 8,000 miles ago and at the same time new MTF box oil! Everything was going so well until probably a month or so in and I started to feel the odd notch when changing gears occasionally. Box was fully reconditioned 6 months ago so happy syncros are top notch "for now anyway!"
This progressed into more aggressive locking but usually only right up at high in the RPMs usually 8,000RPM or so. As time went on this got worse and ended up locking over 7,000RPM so its become a real pain in the a$$!
I've been troubleshooting the issue and naturally started to look into potential clutch disengagement issues. First step was clutch fluid bled and replace, hydrolic cylinders and lines checked and slave piston visually inspected and all operating normally. At this point I suspected either a faulty release bearing or cover or maybe even a bent clutch folk however shifting under normal engine speed worked perfectly!
Before jumping in the deep end and ripping the box out again I decided to just rule out box oil again even though its only been in 8,000 miles. Dropped the oil (didn't measure amount) and filled up just under 2x 1ltr. Took it out for a spin and immediately noticed light smooth shifting and effortless high RPM shifts also! BINGO!!
OR SO I THOUGHT......
A day or so into enjoying my Teg again the notchyness returned and after a good blast yesterday the shift locking has come back when over 8,000RPM.
It doesn't take a genius now to come to conclusion I seem to have a gearbox oil leak and levels are dropping quickly but only to a level enough to cause shifting issues and not to cause over heating etc On this basis the leak has to be fairly high up in the box so I'm thinking drive shaft seals!
Has anyone else had box leaks before and know the common places to inspect? If the bottom of my car was clean then it would be easy to spot but not so easy when its caked with oil anyway from a leaking cam chain cover too
I will to top up oil again soon to see how much has been lost and then race is on to figure out where its coming out of. Brands Hatch 19th of March!! :/
