switch pitch torque converters
I was not sure where to post this because it is old technology and I think mostly a Buick thing. But, I know many people have run TH400 switch pitch transmissions in their Pontiacs over the years.
I am looking for a source of switch pitch torque converters. Is anyone still making or modifying these? Thanks for your time. |

It was a popular upgrade on vintage GMC Motorhomes.

PAE in El Paso, Texas used to be the go-to place. Not sure if they are still around or not.

Sadly, they are not. I grew up learning about muscle cars in that area. I wish they were still around.

The convertor isn't all you need, you also need the SP front pump for the conversion.

DAACO used to have reman SP convertors available, but without the accompanying front pump you can't do the conversion. You need the 2 terminal pass through connector for the extra electrical circuit too. Buick, olds, and some cadillacs had the SP transmission from 65-67 so there weren't that many made, like looking for hens teeth. I actually had one (67 Le Sabre transmission) that I swapped into my 69 GTO, but I never bothered to hook up the circuit for the convertor activation. It went with the car when I sold it. |

Back in the mid '80s a couple of my Buick friends ran the SP Turbo 400s in their GS Stage 1 street racers...
I haven't heard anyone talk about them in years.

My Switch-Pitch Th400 has run low 12s awhile with Street use. I will go through it in March while building a Big Car Case. The converter is a 12" from Kenne-Bell for Street/Strip and the fluid is a nice red. PM if junkin for it. I have no plans to use it for awhile. HIS

Yep, Buick racers in the 1980s is who introduced me to the SP TH400 as well. It's a fun concept to make use of. Too bad it was such a limited production time.
