3sp to 4sp manual

Robert Simpson · 12-02-2015, 11:32 AM

Yes you can replace the 3sp manual with a 4sp manual in stock along with SS. So if you have a 265, 6Cyl comet or 6Cyl Nova you can run a 4 speed. Also for PG optioned stockers and SS can run three speed autos. The above mentioned combo's were just examples. Hope this helps.

Robert, I looked and do not see this in the rule book. Help me out and tell me where it is? I would think the three speed stick to four speed stick would be in alignment with the two speed to three speed auto accommodation.

when I started on this rambler, it had a 2bbl 232 6cyl in it but the 3speeds were really weak, asked nhra about a 4 speed and they said no.
did something change?

James it appears that I owe a appology concerning the 4sp in stock. I really thought that I read it in the updates but I do not see it in the rule book at all. I believe that this would be rather easy to update with NHRA since the auto trans rule is very similar between S and SS, I am refering to the number of forward gears.

Thanks

Robert

This not correct then?
Someone from a concerned party needs to ask why not.

Not as per the 2016 rule book. In Stock the trans rules (For use of forward gears) does not match that of SS for the sticks. BUT for Autos in S, as you know, you can run a metric behind a PG combo etc. But, it looks like until someone ask the NHRA with a letter will allow a 4sp to replace a 3sp maual in stock.

Sorry again Mark.

It's a simple phone call, or email to Danny or Bruce will get the ball rolling. That's why I suggested it be done by Phil, as it directly effects him and his car, he can be specific with the combo that this relates to. It's clear on the auto trans, but not on the stick with the rule.

Seems clear enough to me:

TRANSMISSION, Manual
OEM or NHRA-accepted aftermarket transmissions having same
number of forward speeds (O.D. gear not required) as original, and
reverse, may be used. All gear changes must result from direct
action by the driver. Pneumatic, hydraulic, electric, etc. shifters
prohibited. Floor-shift conversion kits permitted. Clutchless
transmissions prohibited. Clutch must be used to change gears in
a conventional manner. See General Regulations 2:12.

It doesn't make sense to me that stick should be treated differently that automatic in this regard, so I wish you all luck in getting it changed.

Thanks Sean,

I will give Bob a call and find out what I need to do to get this under consideration. I did email him a couple weeks before I posted this thread but have not recieved a reply (email may have ended up in his spam folder).
Car in question is a 62 Plymouth. From everything I have been able to find out Chrysler offered the B-W 3sp in 62 and 63 as their manual trans. I did read they were experimenting with different 4speeds those yrs with poor results. They developed their own 4sp (NP 833) and offered it in 64. I used a DNE in my 64 330 with a 4sp shifter and an additional 5th/rev lever.
