OK – See what you ’63 Jetfire gurus can tell me about This:
I’m in the middle of a total restore of said vehicle and am now trying to get the transmission squared away. I’ve been involved with 3 different cars and they all have the so-called SlimJim auto tranny which is a 3-speed with the terrible 1st to 2nd shift ratio.
I have 2 of these ubits in unknown condition and have just taken them to an acknowledged reman source for exam and reman as necessary. I thought I would be helpful to the reman guy and so I copied the entire transmission section (Section 3, F-85) out of the manual and sent it to him. I also read this section and realized it did NOT cover the SlimJim and instead covered a more conventional 4-speed Hydramatic! I would love to have the 4-speed unit in my car but I can’t find one anywhere – was this just a goof in the manual or are there 4-speed Hydramatics that fit the 215 actually out there?
