need someones take on this, i was talking to a guy today who has a 72-442. automatic with a transmission that was a cross between a 350 and 400. says they only made a limited production of them and they where for drag racing. he says the shift indicator read D S L and the S stands for stripe. his is blown and is looking for another. i never heard of such a tranny but i learn something everyday. what's the sites take on this

 

if anything it's a turbo 375.turbo 400 case 350 type guts,if i remember right the clutches have 1 less plate in em then a 400,and they have a smaller tailshaft

 

I"m thinking he just had a two martini lunch. Hmm...

I thought about the 375, but its a light duty 400 as far as parts are considered.

 

Title of this thread is too funny......

 

 

They all say D S L . The S stands for Super.

 

IF, & I say IF, he has a th375 transmission in his car it definitely did not come from the factory. The only automatic options available that year were th350 or th400. The only stripe must have been on the beer he was drinking.....

 

DSL is an important feature on women too.

 

DRIVE SECOND LOW That's what I'm going with. I know Super was in a 55 Olds 3 spd trans.

 

There was a TH375, which was a TH400 case with light duty internal parts and the small (TH350 size) output shaft. This trans was only used behind the 350 motor in heavy cars, namely the Vista and the Delta 88. The TH375 only came in a long-tail version.

There was also a TH375B, which was a HD version of the TH350 and used the TH350 case.

Neither of these transmissions was ever used in a 442.

 

I'm plum outta S for Strip transmissions but I've got a few R for Race ones left!

 

You can rebuild your transmission, which is the way I would go. You can put in some nice performance parts like hardened hard parts and a shift kit. Its a glorified 350, I have the 375 in my delta. its a 350 with a long tail. Fatsco trans parts stocks a lot of the antique transmission parts.

 

How about some P for passing ones?

 

I think you know by now what the sites take is on this " Special Strip enhanced " transmission .
I have the L on my 76 , but.. I only use it to get home quick if I see lightening .
