I believe I have an A833 4-speed transmission in my 1964 Valiant. Recently, I noticed an A833 being sold with an advertised gear ratio of 1:00 3rd gear, and .79 4th gear, similar to a 3-speed with overdrive. Is this typical for the A833?
That is an 833 overdrive which first came out in the mid 70's to help with gas mileage - remember the first gas crisis in 73? You have a regular 833 4 speed with 4th gear being 1.00. It does not have a "regular" front u joint but what's called a ball and trunnion.
