Slim Jim HydraMatic

[rocketraider]

Since there's a wealth of GM knowledge here, hoping someone can recommend a transmission shop in southern VA- central NC area that is competent with the Slim Jim. It was used 1961-64 Olds all w/394 engine. 1961-64 Pontiac Catalina/Grand Prix.<P>And shouldn't have been used at all!

Well- I was hoping some of you might know a shop that does DynaFlows, figuring that such a shop could do an old HydraMatic too. Most current shops have never heard of one, and the two I've found that have worked on them want nothing to do with it.<P>Anyways, tx for input!<P>Glenn Williamson<BR>the Rocketraider<BR>past Director, ASE Zone (1990-2000)<BR>Oldsmobile Club of America

As you probably know, the "Slim Jim" aka Roto-Hydramatic is a pretty nasty transmission.<BR>The only thing I can suggest is that you try searching through Hemmings (www.hmn.com) and see who may offer services to rebuild them. Also, you can try doing a search on the web and see what you come up with. Also, you can go to either the Olds or Pontiac websites and see if they can recommend anyone.<BR>Sorry I can't be of more help.<BR>Good Luck,<BR>Mark

Well I have the same problem up here in<BR> Maine. All the dynaflow people have<BR>retired and none of the transmission<BR>shops will do it even if I supply the<BR>parts and book on how to do it. I need<BR>seals in my 56 Buick bad so what do we do? <BR>If I can get car up high enough I may have to<BR>do it myself!!! Lots of work restoring old<BR>cars and like you say "no one will do it <BR>anymore" Loren 56 Buick

Rocketraider, I know a guy here in Rhode Island that works on Dynaflows. I know it's a far distance for you but if your interested e-mail me and I'll get you in touch with him.......mrinvicta@cox.net

There is a shop here in my town where the owner (has stated to me) that he will rebuild a dynaflow. I don't know about a "Slim Jim". The name of the place is Consumer Transmissions and it is located in Poughkeepsie, New York.

Thanks for all the recommendations, it seems that getting a pre-65 transmission serviced is a universal problem- hey, I had to have a THM400 done last year and the youngun in the shop had only done one, all he'd worked on was electronic OD trannys. And I realised, they haven't made Turbo 400s in nearly 20 years. Who'd have ever thought those would be considered obsolete !<P>I have a lead on a guy in IL who is very good with HydraMatics, and probably DynaFlows too, but I was sure hoping I could find someone close by to do it, within a couple hundred miles anyway.<P>Guess Loren is right- we have to learn how to do this ourselves. I rebuilt one transmission in my life, a Powerglide, to satisfy auto tech school graduation requirements, and decided better to leave that job to a specialist.
