[Healeys] OD-BJ8----on and on:)

[David Nock]

To start off if the overdrive is engaged you CAN NOT BACK UP. It will feel like the brakes are on and eventually damage the inside of the planetary gears. So if you can back up the car with no problems it is not stuck in overdrive.

When you are operating the lever on the right side of the overdrive are you moving it far enough that you are raising the operating rod. If you are testing in while running  you will not be able to lift it by hand. You will need a pair of pliers to operate by hand.

It's a big problem if stuck in OD. 
You need to verify

  So continuation of my search for OD problem answers.\
  \


  today I jacked up the rear.  put it in  3rd, rev'ed up pretty good---flipped the OD sw---did not engage-----solenoid moving the arm up and down beautifully.  Removed the solonoid piston---ran it up in 3rd--manually moved the arm into 
  OD position---did not go into OD.

  So--OD does not engage---by this testing method I'm not sure if it is still IN OD or not-----last time I drove it is WAS in 
  OD all the time---whether I flipped the switch or not.

  So--------ASSUMING it is in OD all the time regardless of where the switch is--wouldn't that say that it is not a pressure problem??  If not, what could that mean?

  ASSUMING is was NOT in OD as I was testing it, and wouldn't go into OD, could that mean a pressure problem?

  With me moving the arm manually and not getting any reaction would that rule out a solenoid arm adjustment as the problem?

  I'm still leaning toward a pressure problem---caused by----?????  


  Guess next I'll try to do a pressure ck.  Steve---------if you would, please send the equipment.  Thanks

  Appreciate all comments/advice.

  Thanks
  Tom
  PS---before I had the unit rebuilt, it operated beautifully---and I had Red Line MTL oil in it.  I'm thinking of dumping the 30w ND and adding MTL------wishful thinking probably.
