I have a somewhat strange (strange to me anyway) overdrive problem on my 68 BGT with the LH type drive. After driving for about 8 to 10 miles the overdrive engages on its own but only on deceleratio

Someone else probably has the exact answer, but to me it sounds as if this happens with no electrical power to the solenoid the problem must be in a bad seal in the activation system. Keep your fing

What type of oil is used? It should be the same oil as goes into the engine - gear box... See the specs. Cheers, Hans 71 BGT w/o o/d

I don't think we need to open up the overdrive oil discussion yet again. It's enough to say that gear oil (a.k.a. 80 wt or heavier) is inappropriate for an overdrive gearbox. Other than that, pretty

Well I had what sounds like the same problem with my 72B. I also removed all power to no avail. The problem only got worse in the following three to four weeks. A couple of times after a drive I had

The oil pump is running all the time the input shaft is turning in order to lubricate bearings at low pressure, controlled by a valve. When the solenoid operates it closes a port which shuts off the

Hmmm, could it be temperature related? My understanding is you should use single weight motor oil in the OD transmission. I use 30wt. Or... ...possibly the 1st-2nd lockout switch is flaking. Either t

I just went thru the same thing. The problem was mainly corroded connections. The OD solenoid draws about .85 amp at 12 volts, so a few ohms resistance can cause the solenoid to disengage. My car is

The chat about the oil is rather by-the-way for the original poster, and the switch closes in 3rd and 4th rather than opening in 1st and 2nd. I suppose it could be taken to be like the old glass half

Well, excuse me <g>. I know perfectly well how the OD switch functions, but doesn't it strike you as odd why it is called a 3rd-4th "lockout" switch when it does not "lock out" the OD in 3rd-4th, it
