Hey y'all,
Looking for someone who may have some insight into the SD1 LT77 gearbox, or just gearboxes in general.
Ive got a P6 with an LT77 and it's making some unusual noises in 4th gear, like a rattling tapping sound especially at lower revs. It starts under gentle load, gets louder as the load increases then sort of fades out as you accelerate (probably just drowned out by other noise). It also makes a similiar noise briefly as you shift into 3rd from 4th, which makes me think it might be the syncro ring
The box is generally a bit hard work, notchy going into 1st, 2nd and 3rd, especially hard getting into 2nd but it's useable if you're patient and dont abuse it, but I am rather concerned about this rattling noise. It seems parts are difficult to find for this box so not sure whether its worth attempting a rebuild or just trying to source a half decent replacement.
