That transmission was built just up the road on Glendale Ave in St. Catherine’s Ontario.

 

Cool! My son did find info on that 9EL…

 

According to my calculations 3.91 would mean about 2400 rpms vs 3.63 2200 rpm now at 68

 

Question is will that wig out the TCM?

 

So I been looking at few videos about these transmissions and since I dont see a ring and pinion gear anywhere….I dont understand how the final drive ratio is established. Honestly I am far from knowledgeable about automatic transmissions but I dont really consider myself to be stupid but maybe I am….can someone explain to me how that works? I see the chain and sprockets but dont believe that would manage a 3.63 or 3.91

 

Here’s an exploded view of the internal parts

 

Hmmm….got to be final drive ratio between planetary gears….

 

Try copilot?

 

No I havent. Not even sure what it is. That is what my son found info with for me but I never used it.

 

You just ask a question. It is this newgangled AI thing.
