Hey folks --

ok I installed a 200R4 in my 65 442 Convertible. Now it seems the drive tire wants me to buy stock in GOODYEAR because it wont stop smoking... Had friend on phone and he said he could help me out .. Dont know how to delete the post --

 

Yeah, I guess Olds didn't sell that many Anti-Spin pumpkins on automatics back in the Jetaway days. Now, however, your low gear is about a full ratio deeper, so that peg-leg isn't going to make it.


A complete drum-to-drum rear that's been properly set up and is good to go will probably be the simplest way to get both rear wheels turning. Plus, now that you have an overdrive you can go for an even "friskier" gear -- maybe a 3.73 or a 3.90. As for application, although any '64-'72 unit from any A-body can be made to work, in keeping with the KISS principle, I'd look for something out of a '64-'65 -- that way you know the dimensions will be right.


Keep your original parts, though, in case you ever want to sell your car to a purist.

 

Yeah, I would have thought it was the rule for posi's not the exception. Had to change the tranny because the flywall switching gizmo is a dead horse. purist or not ( I was, till this.) I dropped a not so lite money bag to see if the thing could be salvaged but -- They all have the same wear.

Thanks for reply -- if ya have any leads please let me know -- Im an idjit on differentials -- I was gonna say rear ends but this thread would have lit up like Christmas.

 

Well, I'm no expert either -- which is why I recommend replacing the whole thing drum-to-drum. As for finding one, why not post a "parts wanted" ad here on CO?


Not sure what the "flywall switching gizmo" is. Do you mean the Jetaway's switch-pitch torque converter? No matter, you're better off with the 200-4R anyway.

 

Its the bakelite round electrical switch that is attached to the throttle linkage.

 

Well Cores are getting harder to find these days,,,prices going up all the time...
I have all the parts to make yours Posi and 3.36 3.55 3.73 3.90 gear ratio on the shelf along with posi rebuild kit etc. Find some on on your side of the country that can build it. Will be less expensive. 300.00 easy for shipping from Ohio. Jim

 

Oh And the early narrow 64 65 housings are REAL hard to find. So another reason to build yours.

 

yeah okay -- Shifter issues -- so car delayed a few days cuz its weekend. Will take to mechanic next week and see the best combo if thats okay and thanks
