[Fot] Overdrive problem

[Steve Yott]

Dave,
I am sure they checked all the obvious engagement parts and adjustments.  Having 400 lbs. Of accumulator pressure is a good thing.  From there on if its slipping out while engaged in overdrive the the cone clutch is in very bad condition or the brake ring is worn, polished to a slippery shine.  If it is slipping without the overdrive engaged (direct drive) then I would be looking at the uni-directional clutch.  

At my shop with the above situation presented to me I would be pulling the gearbox and taking the overdrive apart to see what is going on.

Hello Friends,
A friend is having problems with a freshly serviced overdrive transmission in his street TR3.  It disengages under acceleration.  
The Brit shop that is working on it can not figure out the problem.  I've been told that it is building a little over 400psi and I guess that is not enough.  
The shop is really struggling with the problem and I know the FOT has discussed this problem before.
I'd like to be able to share tips and suggestions if anyone can help.

Thanks,
Dave H.
