On my hybrid I have rebuilt series transmission with a Fairy Overdrive. Both components work great in my hybrid but the past few months she has begun to slide out of 4th when the overdrive is engaged.
Testing to see if it was the transmission is the culprit, I've driven the hybird at various speeds in 4th direct trying to make it slide/jump out of gear, but it won't. But once I have the overdrive engaged and going down the highway a few miles she will slide out of gear again. I've tried this at various speeds and there was no difference.
With reading on this forum I seen many complain of noisy overdrives but I have to say that mine is quiet, theres no additional noises over that of the transmission. Shifting is perfectly smooth, not binding or grinding. This would lead me to think that the overdrive is not at the point of being worn out, but possibly the coupling clutch sleeve is worn.
I found here: http://www.rockymountainspares.co.uk/?page_id=41 that you can buy an "OVERHAUL KIT FOR FAIREY OVERDRIVE COUPLING".
Has anybody 1) had the same problem with their fairy overdrive? 2) installed the above overhaul kit and 3) cured their similar problems?
Cheers,
Todd.
