Gearbox problems

I managed to completely ferque cup my LT77 gearbox, which was then removed by a garage.
They sent it off through an Indy to Ashcrofts (who I recommended at the start!), and I am sitting here thirteen hundered quid lighter, (including refitting it,) with a totally rebuilt box that doesn't like to engage reverse, first or third, and it's noisy!!
Without getting underneath and taking the number off the box, I can't really contact Ashrofts to see if they have actually done the rebuild!
Anyone any ideas??

If its any consolation, I had a fully rebuilt LT77 many years ago that I could barely drive off from the main dealer - unbelievably stiff, almost two handed selection! - they assured me it would loosen up within 200 miles.....and against all the odds they were quite correct. It carried on sweetly for many years after that. I do hope yours is 'bedding in' - but does sound like you need some serious reassurance for that money and current symptoms. Good luck, A

It's worth a call to Ashcrofts - I think they will confirm the above bedding in period though.

Hi James, The Rev, 1st & 3rd are like having to 'crash the box' as in pre-synchro days, They are stiff and almost need both hands to engage ... I still double the clutch as I have for the past 40+ years, the noise is a whine in 5th, which I would have expected from an old, Series box, and I also forgot to say that there appears to be an inordinate amount of backlash on deceleration, when it feels as though it 'brakes and surges'!
I have never had any of this on boxes that I've rebuilt in the past... but I only did them for 4-speed Series.

are you sure clutch is fully clearing,backlash shouldnt be there

The clutch should be OK as it was only done around 8k back!

Go back to the garage and tell them what the problems are.
It is up to them to sort out the problem.
You have to give them a chance to repair it at their cost.

Does it need bleeding though?

I feel that I have agood clutch which is biting at about half pedal, and I'm waiting for a call back from Ashcrofts.
I'll keep you informed.

Had a call from David at Ashcrofts, who has advised that the lubricant should be Dextron 3 ATF, that the clutch be re-bled, and that the 3-4 bias spring position should be checked relative to the operation of the shift, and that the shim adjusting the reverse travel be checked.
It seems that I will have to take her back again to be put right!!

I've had this problem, due to a badly fitted reverse light switch. Maybe worth taking it out and seeing if the problem remains, then try refitting it.

Thanks for that suggestion.
I'll give it a try later today.

Have you checked the gearbox and transfer box oil levels, it wont be the first time a gearbox has been refitted and the not filled with oil or to correct level.
