TorqueFlite 999 date code same as 727??

Hi All ~

Were the 10,000 day date codes on the 999's the same as the 727's? I just had my 999 rebuilt, and I used the date code for the 727''s which, for mine, came out to be manufactured in '79. But if the date codes are different for the 999, from the 727, then I could have a younger transmission - and like someone reputable in this forum has said, Jeep didn't put in the TorqueFlite in CJ's until '81.

This might explan after I got my transmission back from a rebuild shop, and I installed it, that I only have reverse gear working... The trans shop may have put in the wrong parts... Thinking that my transmission is a '79.

I wish I had the date codes for the 999...

Thanks for any help...

I said look up parts for an 81 because some of the discount store parts books don't list a TF 727/999 until '81 instead of '80 when they are supposed to so you ALWAYS get the wrong flex plate and starter when asking for parts for an '80...
I got handed the wrong flex plate/starter 3 different times looking for TF parts,
When I ordered for an '81 got the correct parts the first try.


The '80 model year was produced well before '79 was over, so seeing a '79 date code on an '80 model transmission wouldn't surprise me in the least.

The Factories usually need a 6 months lead time for assembled units, new model years starting hitting the show rooms in September back then,
That means the foundries were probably producing the cases and hard parts a year before, then shipping them to assembly plants to have those parts put together and tested,
Then the assembled transmissions were on the AMC assembly line about July or Aug, so the new models could hit the show room in Sept. of '79...


Only having reverse could be a few different things,
Sticking sifter valve in the valve body,
Roller clutch put in backwards, are a couple...

That VEHICLE would go to the shop I had the transmission built at,
And THEY would pull it and fix it if I were you...
That's why you go to shops, to get WARRANTIES, To get PROFESSIONALS...
PROFESSIONALS will warranty their work and they will make you happy at all costs if it's their fault!
