Hello all,

I have a bit of a problem with my T5 gearbox i would like to run by you before it goes for stripping, in case it is a simple fix

When I try to make a quick change from 3rd to 4th gear, the lever kind of seizes in neutral, and when the engine speed drops to roughly 4000 rpm it goes into gear easily. The box does not crunch any gear, and even if I try to force it, it will not get into gear, nor will it crunch. It just stays stuck in neutral.

If I try to make quick changes at high rpm, but with no load, it goes into any gear with no problem and it is also on the standard lever

I have changed the oil in it for new castrol dextron 3 ATF, it made it a bit better, but no cigar.

Power wise I am currently at 270 horsies at 1.1 bar of a standard engine/turbo set up

Any help appreciated

Thanks
William
