4+3 Question
How hard is it to wire the 4+3 up so that it only comes on when you want it to. The only time I ever use it is one the highway and its kind of annoying when it shifts into OD around town, I usually try to catch it before it shifts, but sometime I am not quite quick enough. So if its an easy thing to do and you want to write the directions down that would be much appreciated...thanks

It isn't hard. You just have to run a switched 12v source to the overdrive solenoid on the overdrive unit.

Check out the Feb. '03 issue of Corvette Fever Magazine. In the Wear & Tear section that this exact question is answered. It's in the "Neurotic Overdrive" Q & A. I am going to do this on my '84 this weekend. :cool:

Re: (scorp508)
ATT: Scorp508...Can't say that I agree with your suggestion to just use a switch to turn the OD on and off... I would route such a swtich through a reverse and 1st gear lock out. Reversing in OD, as I recall, doesn't work as there is no pump pressure and the OD wasn't designed to take the torque of a hard 1st gear start.
I just try to remember to push the button when I start or shortly there after when it goes into OD when I don't want OD. The inconvenience is a lot less expensive that an OD unit, Right Scorp? You should know!
