Droldslives Posted August 16, 2006 Share Posted August 16, 2006 My 1968 cutlass has a two speed jetaway transmission in it and I would like to know if the two speed jetaway is the same as the GM two speed power glide? Also, is the model number for the jetaway transmission TH300? Thank you. Tim Link to comment Share on other sites More sharing options...
vegasdelta Posted August 16, 2006 Share Posted August 16, 2006 Hello Tim, Your jetaway is completley different from the powerglide & is the TH 300. Good luck with it. Jerry. Link to comment Share on other sites More sharing options...
joe_padavano Posted August 25, 2006 Share Posted August 25, 2006 Actually, to be completely correct the Jetaway is called the Super Turbine 300 (ST300) and was used in Buicks and Pontiacs as well as Oldsmobiles. Only a few parts are interchangeable with the Powerglide. Link to comment Share on other sites More sharing options...
RShepherd Posted October 18, 2006 Share Posted October 18, 2006 Unfortunately, it shares one annoying trait with Powerglide: the 'whine' while in Neutral or Park. Link to comment Share on other sites More sharing options...
Guest 1963starfire Posted October 19, 2006 Share Posted October 19, 2006 What causes the whine, while in neutral or park? I have a '63 Starfire that does that. Is that considered normal? What causes that?Thanks Link to comment Share on other sites More sharing options...
rocketraider Posted October 19, 2006 Share Posted October 19, 2006 It's really not "normal" but with Slim Jims, "normal" can be very widely defined... <img src="http://forums.aaca.org/images/graemlins/laugh.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest 1963starfire Posted October 20, 2006 Share Posted October 20, 2006 I know your right! According to the shop manual on the '63 Olds in the Hydra-Matic section undernoise diagnosis:Buzzing noise... (possible causes) 1)T.V. valves 2)Governor3)Pressure regulator valve Link to comment Share on other sites More sharing options...

And that's how I know it's working good. I changed the filter last year and it didn't seat properly, so it wasn't pulling fluid out of the pan. No buzzing. Also no gears. So I drained it, took a BFH to the filter to get it seated, and started to refill it. I knew I was OK when it started buzzing...Paul Link to comment Share on other sites More sharing options...
