Can any tell me if this transmission is a "freeway flier". Here are the numbers stamped on it. Thank you.
This number is stamped on the case of the tranny.
vw 113.301.103L
45 is under that number.
And this number is on the side plates
113.301.183F
And another number
AT 28 11 2

I'm pretty sure "freeway flyer" is an aftermarket name, so the numbers are now meaningless.

Does it have a 5th gear?

The guy claims it came out of a 73 super. So I am trying to figure if it's a freeway flyer. He bought the car as a project and doesn't know much about the tranny. It was already out of the car when he got it.

What is your tire size?
Then:
Hook up a tach, and a gps, and tell us the speed of the car on the freeway at 3,600 RPM. Then tell us the speed of the engine at 60mph in 4th gear.

Your trans should have a 2 letter code on it, which will tell you what the originally installed gear stack would be.

I am looking to buy the transmission off the guy if it's a "freeway flyer". So I am trying to identify the numbers.

Unfortunately, the numbers only tell you what VW installed in it in the seventies. Unless the seller has a receipt from a transaxle rebuilder shop showing the gear ratios with a serial number that matches the transaxle, there is no way to tell without measuring the input shaft to output shaft ratios in degrees.

If you are willing to get a little dirty, put the transaxle in fourth, and spin the input shaft EXACTLY one turn. Count in turns + degrees, using a protractor, how much the output flanges turn. (Do both sides and make sure they are identical, so you're not getting any differential difference.) Then repeat the test, but this time spin the input shaft four times, and count the number of turns + degrees the output flanges move. Do each side. Report back.

Unfortunately, unless you have x-ray vision, there is no other way to determine this. Fortunately, freeway flyers reduce power, reduce cooling, and reduce oil pressure, so you probably don't want one anyway.

Freeway flier is just a marketing term. It refers to the 3.88 r&p and .89 fourth gear VW installed in later cars. I believe VW changed to these gears as highway speeds increased in the 70's to lower cruising RPM's.

Find out what the two letter code is on the trans and we can tell you if it originally came equipped with the 3.88

The AT code matches the 3.875 R/P from the 1973 Super Beetles (1303), provided that the transmission is the original and has not been rebuilt with different R/P and/or gears.
