[TR] Sluggish Overdrive take-up

[Mack, Michael (Rochester)]

This question probably pertains to all Triumphs with Overdrive units.
I recently replaced the Clutch in my  79 Spitfire with an AP 3 piece kit.
While I had the tranny and O/D out, I replaced the tranny oil with 90w GL1
Ford Tractor oil.  I was trying to stay away from GL5 oils that would eat the
copper/brass pieces in my J Type O/D unit.
Now that it's all back together it shifts nicely, but the electronic O/D
engages with a delay or not at all.  It disengages sluggishly too.  I tested
the solenoid with a hot wire directly to it and it clicks each time.  I
cleaned up the bullet connectors on the wiring also.

What do you think is causing the lag to engage the OD?  Wrong oil? Gremlins?

Thanks,
