My GMC Master Parts Manual says that your 253 model 
should have a 210U Hydra-Matic.  The markings are found 
on a tag just above the rear side of the transmission pan. 

My 177CA Hydra-Matic is marked something like 
"57-CA177 xxxx" where 57 is the year, CA177 
is the transmission model and xxxx is the 
serial number.  I have never seen the xxxx match 
any VIN number, so I don't think that there is such 
a thing as "numbers matching" GMC TF trucks.

By the way, I did a little follow up on your VIN 
question from last week.  The 253 model is a 135" 
wheelbase 1 ton.  There were also 251 (114") and 
252 (123") models.  Rear end ratio was either 4.56 
or 5.14 to 1.  The Master Parts Manual claims that 
the Y model (55) was shipped with both the 288 and 
316 V8.  Based on your low serial number, I'd bet 
that yours was a 288.

I have possibly located a hydramatic transmission for my
truck, and need to know how to positively identify it. Are
there numbers on it somewhere, maybe someone has a picture
of one, any ideas? The tranny is in CA, and I'm in NM.
