Whats my gearbox

[Rich]

Good afternoon all,

 

After an afternoon fettling changing gearbox oil and overdrive filter i was intrigued to see what gearbox i actually have. I looked at the numbers but where unreadable, the only number i could see was P128? The overdrive is a D type.

 

Thanks in advance

 

Rich

 

P.S the reverse is left then up also  on the gearbox

Late single-rail boxes have reverse forward and right, where 5th would be in a modern. They are Marina--derived and have the BL "plughole" log cast in to the alloy, and in O/D form come with J-type Laycock overdrives. Not a bad box either, contrary to what your read, especially if the plastic selector bushes are renewed...

Left and up/forwards is a 3 rail family selection

those numbers are not triumph related

should be stamped on the top face of the main case alongside the alloy top cover

so only visible with the tunnel off

Hi many thanks for the replies,

 

The stamps were unreadable Pete but i think its a normal 3 rail (can see 3 rails) triumph box with a D type overdrive.

 

many thanks

Yes you can see in the top cover the caps that seal the three selector shafts

 

On a 3 rail one shaft carries the 1st 2nd fork, the middle carries the 3rd and fourth fork

next takes just the reverse fork

There is a , ward, on the remote that toggles between them

 

on a single rail its is it says just one shaft with all 3 forks located on one central shaft

the remote tower is a little more complicated and the selector has a ward for each fork

which has to rotate to engage each fork.

 

 

In the end that may be some reconditioners ID

but 3 rail and D type sounds just right

New to this site.Recently purchased a 2 litre,  with overdrive, vitesse convertible  needing fettling.[G reg.].

Bought a gearbox [inside car] cover to find that the hole for the gear lever is about 1.1/2 inches forward of the actual lever.

Also new carpet set is similar in that again the hole in carpet is 1.1/2 inches forward of  the lever.

Have I got a wrong gearbox.? The car drives ok with it as it is just the hole problem.

You could have got a cover and carpet for a Herald not a Vitesse.

 

Is it a three rail, reverse left push down left again and then forward, up by first.
