We need some help figuring out exactly which trans we have in the Dart. The bellhousing has A904-LA cast into it. The TIN is JW161150. This trans was advertised as an A999. What are the differences?

Thanks.

What other serials numbers are on the oil pan rail and this tranny is very simular to a A500 with the overdrive and lock up controled by the TCM,mrmopartech :compress:
 
I'll take a look and post them later. The car is at school now. From what I've read it sounds like the case is the same for a 904 and 999. The gears are the difference. Is this correct?

Thanks
Ken
 
The 999 has a lower 1st gear then the 904, but yes they are the same case.

The Transmission Oil Pan has a half legible number on it. It looks to be the following PK4446866 9??5 5069. The ?? could be 70 or 30 or maybe 79 or 39.
 
Thanks Justin. Justin is another member of the motorsports team.

We have the front of the trans taken apart. When we get all the internals out, what will the A999 ratios be?

Thanks
Ken
