I'd buy it for that.
What's the VIN# stamped into the machined pad on the drivers side,just above the shift linkage behind the rubber boot? Can you read the Pass. side aluminum tag as well? |

I wanted to reply to your question in the 6-lug convertor thread about this TH400,so I thought this topic was better. The 1970 CW is a seldom seen scarce Transmission. 1970 CW TH400 was designed for specific Solid lifter BB & SB Applications. They were: *Chevelle-Nova-Camaro L-78 402/375HP. *Camaro Z/28-Nova LT-1 350/360HP Yenko Deuce. Not knowing it's overall condition,I'd say it's worth the 1K regardless. |

I have the CW coded trans in my 70 Z28. What is different about this transmission over a CX or CY tranny and any other unique features. It also has the 6-bolt converter.

1969 Camaro & Chevelle used the CX TH400,as well as other solid lifter applications.
1970 was new for the CW suffix TH400,in the L-78 & LT-1 Camaro-Nova-Chevelle. |

To Wilmasboy:
My research has said that the design upshift speed at WOT of the 69 CY trans was 5900 to 6100. The high speed governor will help you up your shift points but also affecting shift timing are line pressure and accumulator springs and pistons. Also the trans was designed for hard use as all wavy shift plates from clutch packs were removed for harder as well as quicker shifts. Some other mods were the forward clutch drums have 2 oil bleed check balls instead of 1, this allows oil to dump faster to speed shift timing. The 6 lug convertors were first used in trucks so you can find trucks with the same convertor shell but everything inside is vastly different. Frank |

I believe it's gonna be the same...except the converter is different, which according to Ray Morrison flashes in the ~1800 rpm range...

Here's the tag on a "CY" in a neighbor's all-original '71 LS-6 Corvette:

Frank [/ QUOTE ] Frank, I recently found a 69 CX THM400 out of an L/78 Nova. I now need the correct 6-lug converter. I see them on eBay from time to time, but you comment about the truck converter being vastly different concerns me. How does one know if you have a true SHP 6-lug converter? Or, are they still available from GM with the proper internals for an L/78? ![]() BTW, were the SHP converters stamped or coded in any way? Steve
