Maineah - Yes, the O/D light comes on but the O/D still engages. Is the O/D solenoid located in the transmission? Derek up North - Response 1. - are you saying Many/most advocate never using the A43 transmission or the O/D in the A43? If the O/D, that's what I'd like to be able to do - not use the O/D. Response 2 - I had not been aware of the altitude switch until I saw a note about it in one of the other subjects in this forum. As much of my driving is above 3000', evidently this lock-out switch is not working either or it's unable to override the failure of the O/D lock-out function. Thanks for the quick responses!

I've been reading this forum for some time now and have found it quite helpful! Thanks to all for making this happen. My question - on my 89 Toyota, 22RE engine, the overdrive kill switch is not working properly in that it is failing to lock out the overdrive when activated. I'd like to be able to drive (in Western Montana) without the overdrive kicking in every time I reach my desired speed on a slight incline, only to have to push the gas pedal down to kick the tranny out of overdrive because I've dropped too much speed. Sometimes this can go on for miles on end, especially on an Interstate that's following a river upstream - which happens at least 50% of the time in these parts! I've been told by a local mechanic that the transmission would need to be taken out in order to check some type of sending unit. As an FYI, the cruise control is also not working but I really don't need to have it working. It's just that the 2 failures might be linked. If anyone out there has some suggestions for me, I would appreciate your thoughts. Thanks in advance.
