hey yall im having trouble identifying a transmission that has already been pulled off a truck. Its wither an A440f or an A442F. not sure. can i use the first two digits of the serial number to identify the year and month?

I posted on mud but no one seems to know/care. see the pics below.

also here is a toyota service bulletin for new model transmission and how to decode the serial numbers.

I don't see the TSB :confused:

Not that it would help me help you anyway :hill:

Are there any exterior differences between the two? As I understand it the A440F is hydraulically controlled while the A442F is electronically controlled...Seems to me that the A442F then would have some differences like plug(s) for electronics? Tells you what I know though :)

Came across this link in a search...

Various manuals including maybe one to the A440F and/or A442F via Torrent links...Search on A440F


Post #97 in this thread might help?


It has a link to the A442 Transmission Manual: http://www.mudtoys.com/manuals/RM314E.pdf

Finally, I'm not sure but TSB #TC00496 just might contain the data you need for serial code deciphering...I don't have access to TSBs though

Didn't one of those trannies come in an FJ62? If it did I bet you could try posting in the 60 series section if so. If not, I bet Robbie or Jim C. could help you.

I can not tell by the number. But as stated, the 440 is a mechanically controlled tranny. Where the 442 is a electronic controlled tranny. So on oppisite side of where the shifter is hooked to shifter, will be a almost triangular electronic switch with a wireing harness out of it. that is the easiest way to tell the difference.

Now with the 440 you have two types, one that fits the 80 series trucks and one that fits the fj62 series. The 80 series style with have a short out put shaft, with no threaded end, where the Fj 62 one will have a long out put shaft, what a threaded end.

Hope that helps, Take a few more pic's of the out side where the shifter hooks up to and the tail shaft. That will help me to identify it better for you.
