Hey all,I am trying to find out what type of transmission i have..the truck it is in is a1987 d100 pickup vin 1B7FD04T2HS518761 and the Transmission has numbers stamped on the driver side just above the pan they are PK4431554 9443 8133 i dont know why there is a space between the numbers but any how your help is greatly appreciated....

all ive ever been able to figure out from that number is that that the 9443 is a 10000 day date code.

i regularly get theseconfusd but to best of my knowledge here goes


3 spdauto is A727
3 spd auto with OD is A518 (which is basically a 727with a couple vaccum lines i learned the other day.)
so just look at your PeRNunDeL and count the gears

also there was the A500 which is a3 spd + OD andslightly different gear ratios (from 727/518)that was NOT used on your truck because they started in like 89 or something

thanks for the info nemesis i justfound a web site that has an online automatic transmission reference guide. here is a link to the guide check it out andtell me what you think. is the info accurate? http://www.drivetrain.com/autotranscrossref.html#DODGE

yea these make sense only they use the new code. instead of 727, 518, 500 they use like 36RH 42RH etc (i dont know them exactly).

the first number is number of gears
second is torque rating (from 1-8)
first letter is R for rear
then H or E for hydraulic or electronic control system

PS, "T" does not mean linked to a Transaxle it means transverse mount. So buying the 31TH from somebodies Omni isnt gonna give us 4x4

My 87 has the 904 in it. Just thought, it has the lock-up converter so it may go by 999 or something. It is the light duty one though.[sm=americanasmiley.gif]
