I need to order a new driveshaft. My question is the yoke that connects to the T400 tranny. I understand there are 2 types of yokes. A slip-on yoke or a bolt on yoke for trucks that has a O-Ring seal on the tranny output shaft. I do not know where my T400 came from so can someone look at these pictures and let me know what you think? I am thinking a T400 slip on yoke, not threaded. I called tech support, but the guy was getting frustrated with my lack of knowledge about my T400.

 

Looks like a slip on to me as most are.

 

thanks
