C-6 428CJ torque converter
« on: August 07, 2023, 07:16:22 PM »
Looking for specs on the stock torque converter for the R servo C-6 transmission. Finally found the correct C-6 not sure I trust the old converter attached to it.

Thanks!

I've used these behind three 428CJ / C6 equipped cars. They work well.

Hmmm going to have to give some thought to where one might find the stall speed and other original specifications for any of the torque converters.  Good question

The shop manual provides that information.
