what exactly? overdrive? Not in the heavy dutys! that started in 92 or maybe 91.5
There may have been a light duty overdrive, and i know there was a light duty gasser only unit with a lockup converter, but since were talking about very powerful engines, i was referring only to heavy duty units.

Absolutely! I bought the 1993 in my signature for a number of reasons, but a big one was that it was equipped with overdrive. My old 1991 did not, and she was really wound out on the highway!

Thanks for all the inoput...I would rather just repair the Gear start twin...however there is no one around here who has even heard of it...having said that; the transmission has been rebuilt and does not shift correctly warm, it wil be late to up shift and I am looking for a temporary install while that is sorted out..
I suppose I will have to figure it out Cheers all!

If only when warm, then sounds like a worn bushing didn't get replaced. If both cold to some extent and warm, then check the throttle linkage adjustments carefully--actually, a good idea to check adjustments anyway and reference the later service counselors for the procedure..

OK so I adjusted the mechanical linkage exactly how the manual says, I was not getting an upshift from D' ...so I adjusted my valve body throttle valve screw with information from PP.
Now for the first time in 20 years this car is upshting!! However it has a slight rattle type noise from the front pum/torque converter area....any ideas guys?

I believe there was one correction to the shop manual WRT to the throttle (valve) linkage, plus other variations and additional checks specified in Service Counselor and/or Service Technical Bulletin.
No mattter what aspect of the car you are working on, after reviewing the shop manual, be sure to check this website's Packard Service Index feature. As for noise, if you are sure it is coming from the front of the transmission, I'd suggest removing the lower cover to inspect the flywhell/flexplate screws. If you haven't done so already, that might be a good time to drain and refill the trans fluid - including the converter. If you remove the spark plugs from the engine, you'll find it easier to rotate the converter and access both of its drain plugs.

If the rattle ONLY happens during the transition to direct drive, then that is most likely the DD clutch slipping a bit when engaging--somewhat normal on trans with old hardened clutch plates not used much. When it comes time for shift point, let up on accelerator while it shifts and if noise not present or greatly diminished, that is problem and some driving, possibly use of the trick shift fluid or in worst case, new clutch disk will probably make it go away. If the rattle is there all the time, then I'd check for something loose.
