using the T5 tag id number on this site I inserted the last 3 digits of my tag number from my tranny (066). And it Identified it as an AWSF 1984.
Does anybody know what this means?

[Twister]

what year is the tag?

[coondog240]

tag reads E3ZR E stands for decade F is 90's E is 80'S C is 70'S and D is 60's. so we have 80 the 3 stands for the year 83 z is the car code Z is mustang R is the locacion of assembly werever that might be. Is that correct.

That means '83 and up Mustang.

R = Chassis & Transmission Engineering Division (manual transmission)

R is the Transmision and Chassis Division, Manual Transmission, if it was a P, it would be an auto. Above the E3ZR, it should also read REP-AB for a 302 T5, or REP-AA for a 2.3's. Next to that number shoud be the date code, something like 3A12 for Jan 12, 1983(last digit of the year first, followed by a letter for the month, skipping I and O, then the day of the month). Below the date code should be the tranny serial number. It is very possible to have 1984 as part of the SN, but the AWSF is throwing me for a loop. AWSF is a Motorcraft prefix for a type of spark plugs.

Are you sure it's a 5spd?

We pulled a cast iron ZF 4 spd out of my son's 85. Sure wish I had kept it

With the E3ZR stamping on the tag, the only 4 speed that it could be is a SHOD and the identification code would be RUG-EM

[FoxChassis]

SHOD?

[Twister]

oops, SROD-Single Rail OverDrive...after a long day in training, I messed up

[FoxChassis]

An SROD wouldn't have an E3ZR prefix though. It's an '83 model T-5, almost definitely.

it could, the last of them were made in early 83

[FoxChassis]

Unless the design was changed, the service part number prefix (E3ZR) doesn't change either. The SROD's design went basically unchanged for the entire '79-'83 run. So then the service part number prefix would be D9ZR.

So many people think the service part number prefix on parts changes every year, i.e. E3xx in '83, then E4xx in '84, then E5xx in '85, then E6xx in '86, etc., etc. It doesn't work that way. Look at '87+ H.O. 5.0L cylinder heads....E7TE all the way through '95 (exc. GT-40 and GT-40P). The date code changes, since it designates when the part was actually made.

Besides, transmission ID 066 isn't a Tremec code, it's a BW code.

This whole mystery could be solved if we could get ALL of the data from the tag instead of bits and pieces of it.

we are talking about a tag here, not the casting number. If you look at tags you will see that they change each year, not like the casting numbers.

[FoxChassis]

E3ZR is a Ford service part number prefix. "Casting number" is slang for service part number prefix because it happens to be cast into a part instead of stamped on a tag (as is the case with transmissions). Service part numbers DO NOT change unless the part changes.
