will a 4speed b&m shifter combined with the stage 3 mv valvebody upgrade allow me to ratchet all four gears?up and down?....i was told you can only ratchet the 1st three, and fourth always has to be relayed to a switch(for overdrive).....is this true?>if so why does it have to be this way???

Looking at doing the same thing myself. Looked into it a bit, u will have to fit a 3 speed shifter and then wire up the o/d somewhere. U will be able to ratchet the first 3 gears, but have to play the o/d switch for forth.

No 2 ways around this as far as i am aware.

exactly what i was told

Another thing u could do would be use a 3 speed shifter and wire up the o/d via missile switch or something.

Then u could ratchet the 1st 3 gears, but the o/d we constantly on, therefore 3 to 4th occurs automatically. Which defeats the purpose of having stage 3 if it only does some of the gears.

Had a look at a car this arvo with this set up and the owner assures me it works as its intented, an he said the o/d thing isnt that big of a drama at all.

thanks for that, where was the o/d switch placed in his car?was it relayed to the power?

The o/d switch was located just to the right of the shifter. Relayed to the power - i didnt ask

Use a 3 speed B&M pro ratchet shifter with the optional button knob.

This is what I will be doing soon and should make switching to overdrive a breeze.

Here is a link to the button knob.

You can't leave 4th-o/d constantly on, as this interfears with 2nd, trust me I tried this for daily driving.

If you go stage 3, it is manual shifting all the time.. including the switch.

Trying to sell my car, but f**k it, i am gonna order this electronic lock out box in the next week or 2 and report back here.

I have a B&M megashifter, can ratchet the first 3 gears, with the O/D wired via a simple on/off switch.
