64Imperial

I have a 64 imperial im putting a bigger cam in and need a higher stall. how ever noone makes 19 spline converters. I found this article but i don't know if it is all there or missing information? or maybe its the pictures i don't understand cause i know nothing about transmissions.

http://www.hotrod.com/how-to/transmi...que-converter/

what parts called is it talking about that need changed?
Are these able to be bought new from a local auto store or online?
If so how much these cost?
If i buy them used from someone whats a good price?
and what would it cost to have a transmission shop such as tanner transmissions to do this work for me?

sorry for all the questions. just need to know it depends on the cam im able to run in my engine, im upgrading to a 440 using 906 heads stock 2.94 gears ( might change them to 3.23s )

One more question if i change to 3.23s and use a taller tire ( i plan on fulling the wheel wells with aftermarket wheels and tires 18" rear and 17" front i'm thinking ) how much does this effect your actual ratio. just as a example say i have stock tire size 23" tall i have 2.94 gears i change my gears to 3.23 but put on 26" tires how far would that lower my gear ratio? would i be back at 2.94 again? or does that make my ratios go up with a larger tire making me like 3.5? just as an example idk if there is a formula to figure this out im sure there is

Thanks in advanced!

With my limited knowledge of older transmissions You would need a complete rebuild. As the main shaft and the front pump would have to be replaced, requiring complete disassembly.. You would be better off contacting one of the converter re builder and have a custom made converter

damn i thought it would be an easy thing seeing they said " any competent transmission shop can duplicate the results for you if you're not ready to do it yourself. "

Maybe I don't know how to operate the internet. Seems to me most of the guts of that article is missing, or I can't figure out how to navigate the thing.

IF you are comfortable doing work on engines, IE complete assembly from a bare block, and understanding checking clearances, it's likely you can easily transition into Torqueflite overhaul.

First, there's a series of free videos on YouTube that are very good: There are something like 19-20 of these, and if you get an add on for Firefox, etc, you can download and save them


Next, buy the book by Munroe if you have not

Yet another source with useful info are the ATSG series books, but they are slanted more towards experienced techs

And, certainly NOT least and possibly most, is the original, OEM Chrysler service manuals, which you can download FREE from MyMopar:

So far as parts, Cope transmission, "Torqueflite Patty" on Ebay. There's actually quite a few well known transmission "guys" who sell parts and or build these

I would send it to A&A Transmission There is a lot missing from that article.. OR put a floor shifter in your car and used a later trans. Either option will be expensive

ill probably just change the cam and not get the sound i wanted. and not mess with it. thought it would be an easy fix change this part with 19 spline add this part that has 24 and done thats how i thought it was going to be. but seems its not.

red67

you need to talk to A & Reds transmission. Wichita KS. parts they sale to 95% of ALL the trans shops and over seas. they can answer ANY Q you have and will have the parts. i have known them from the late 60s. they even know what an M6 trans is. http://www.areds.com/

Coronet 500

How about this.

wow thanks, i looked all over for one even called a couple places and said they cant even make them.. that 2500 should work for me perfect looks like ill have to change the rear gears to 3.23s though but yeah.

if i change the converter to that 2500 are there any other parts that might need changing? i heard these trannys are pretty much bullet proof.

anyone know if there is a difference in any of the 8 3/4 rear ends? or are all the eternal gears the same for them rear ends you just have to pick a ratio you want? cant seem to find anything that said for "imperial rear end" but says 8.75" im assuming the imperial 8.75 is the same as all the others gear wise & i can buy any 3.23 gears that fit it? found some for 285 bucks with a 2 year warranty

just called billet converters they seem to be out of business? number was out of service.

Maybe you should just stick with the gears you have until you sort out the rest of the powertrain? I believe there are three different 8.75 pinion sizes.

Have you ever heard of "Google"

The larger the rolling diameter, the lower the effective ratio is. If you have 235/75/15 tires, you have about 29 inch tire. If your new rolling radius is 10% larger, your effective gear is 10% lower (i.e., 2.94*0.90). If your rolling radius is 10 % lower (smaller tire) it is the opposite (i.e., 2.94*0.1).

okay cool thanks Demetri. looks like wheels size doesn't effect the gear ratios / rpms on the freeway by all that much then. im not sure what tire size im going to go with as of yet it will be a taller tire cause i hate the rubber band tire look. i like lower profile but i still like sidewalls. im looking at running 17" in front and 17 or 18 in rear depending what i can get away with side wall wise. i still need to figure out my back spacing and all that im plan on changing with a spacer adapter my lug pattern from 5 x 5.5 to mustangs 5x 4.5 for more wheel options i found wheels i want but have to see if they will even work.
