Bought a brand new 73 MGB Roadster and with overdrive have not had a minute's problem with any of that it's been a great little car I could not imagine it without Overdrive
Interesting setup. I never had an MG with overdrive so never had need for this kind of testing, but good to know how it can be done. I wonder how difficult it is to adjust the rev/1st/2nd lockout.
I need to know it the MGb 1979 Overdrive transmission use diferent Clutch Plate ? Because I change the the 4 shift transmission for Overdrive transmission and the car do not take the shift. Thanks
Dumb question guys. Why is it so important to have an O/D lockout? I have driven 5 ton trucks with 5 and 2 shifters,not using the upshift is optional when empty or downhill. Could an experienced driver rig so as to have the O/D permanently available? Is this advantageous? Inquiring mind wants to know. Thanks.
Paul: the two-speed axle in a truck is meant to be used in (almost) all gears, but the Laycock overdrives are not. The lockout switch is designed to protect the overdrive in lower gears, and especially reverse. Another factor is that the oil pump for the overdrive is driven off of the gearbox output, so it takes a long time (as you can see in this video) for the overdrive to engage at low speeds. Lastly, the overdrive is not very useful in first or second gear (it's easier to just shift to third).

Great video , from memory, The Laycock overdrive was electric control,
I take you guys are testing the solenoid , for function.
