OK first off this is going to take me a little while to get all this on here. I'm going to put every thing I have about matching up transmission numbers. I got some of this info from a family member who works at the transmission plant in Kokomo Indiana,and the rest from different places. A few things to remember when looking for another trans. In mid 99 they changed some of the electronics.96 and up A500, A518, and A618 use the same governor pressure solenoid. 96-early 99 A500,A518,and A618 use the round metal pressure sensor or transducer as some call it. Late 99s and up use the black plastic 1.
96 -early 99s use the same OD & lockup solenoid. late 99s and up use the same OD & lockup solenoid. 78 -98 uses a round black neutral safety switch with 3 pins.For 99s they changed the neutral switch to a rectangular white plug with 3 pins. In 2000 they changed to a 5 pin big plastic switch
If you look above the pan on the drivers side there will be some numbers stamped on the case most of the time they start with PK. The next 8 numbers are the part# for that transmission. Also if there's fins above the rear servo it's a A618. Diesel and V10s have a moon shaped cut out at the bottom of the bell housing for a bigger torque converter.

this is 1 I'm cleaning up and waiting on parts for. Holidays are making the mail run slow, but should have it built by Friday.I will post more numbers later if I get this 1 clean and a 47RE built.

 

A618 at the top and A518 at the bottom. notice cooler lines are different.

 

A518 on the left A618 on the right

 

A618 on the left and A518 on the right.figured since I had the 2 cases apart at the same time I would post pics for those who don't know the differences

 

Sorry for taking so long on this. My HD crashed on my laptop and I have had to put all my backup files on a new laptop. Total pain in my A$$. I will try to get more numbers on here this weekend.

 

Thanks for pisting the data in December...I was relocating and missed it. I have seen the A618 on WITTRANS website, so I knew it was a variation on the 500 series tranny.

What does the 618 fit? Just curios.
