Trying to see what MPG/ Miles Per Tank yall are getting w/ your transmission setups.
I currently have a LS trans and range from 290-320+ on a tank…26-30mpg. Not now, but soon i will be needing to change my transmission because i hear the bearing in it making a little noise. I’m trying to make a solidified choice on what to do as far as a transmission before it goes out…and i can maybe start gathering transmission and clutch parts for it…
Thanks in advance, folks
your MPG seems to be about dead on with mine. I also am running an LS setup A1 cable transmission B18A1… I do have AEM CAI & 4-2-1 DC street header, but even with those added my MPG is about the same as yours…
According to Edmunds, EPA mileage estimate is (cty/hwy): 21/26 mpg., keeping in mind this is for a new car. I got about 28 after my recent tuneup adventure, with new plugs, new timing belt, timing set right on the mark, and premium gas, based on about 50/50 city hwy.
edit:
Oh, and, no engine mods. I do have a 60-mm exhaust, but with the stock cat, any effect from that on power or mileage is pretty insignificant.
Averaging 27-30 mpg with the short-geared ys1 but I keep it under 3.5k rpms and coast whenever I can.
are you turning 3500 at 70 mpg TegFan?
only ‘mod’ i have is a ebay catback, only reason i have that is because the one i had on the car when i bought it was complete shit/rusted out/welded horribly
3500 at 60mph, 4000 at 70mph
and still 27-30 mpg…nice
one other question. how are you supposed to be able to decipher the long geared vs the short geared YS1 trans?
Havent done it myself but you have to open up the transmission case and count the tooth of ring gears.
I got lucky and had it paired with the B17.
Also I forgot to note that my tires are 195/65r14 instead of the recommended 60 series. Odd thing is my speedometer and GPS speed are showing the same mph. Just bought some new 195/60 so well see what will happen to my mph readings.
[QUOTE=TegFan;2279209]Just bought some new 195/60 so well see what will happen to my mph readings.[/QUOTE]That would only translate into a 3% difference. Tire pressure, and new v. old tires can make close to that. I went through this with a friend of mine couple years back. In the end he had to put his old wheels/tires back on the car to persuade himself he wasn’t driving in the Twilight Zone, chuckle.
I suspect on most cars like this, new-ish plugs, correct timing, distributor, O2 sensor… make a much bigger difference than anything else.

Do it the easy way…
Are you at these matching RPM/MPH? Or do you have higher MPH at these matching RPM? That will get you your answer.
Taking your case apart is a good experience… but you can use a transmission calculator or match RPMs like I said.

meaning?..
cuz i thought there was supposed to be like a certain number or something after the “YS1” code on the tranny
I get about 23-24 MPG all city, but I moved and I am closer to the highway so I use it a lot more, so my MPG is probably going to change a little bit. I’m running a stock b18A1 DB automatic with the only mod being a CAI.

I’m sure those numbers will tell you, as they’re the serial number… But I dont know which serials are for what chassis.
I explained the easy way…
TegFan said he has a short gear’d transmission, that’s why I quoted him…
In 5th gear, at 4,000rpm he is at 70mph. Get in your car, hit 70mph in 5th gear, and look at your RPM. If youre at a lower RPM, then you have a long-gear transmission. Fairly simple.

your “easy way” is replacing my LS transmission and hoping that the LS trans i have is short geared/long geared…which includes labor and cost of another transmission. i want a ‘prior to’ way of finding out which YS1 trans is short and which one is long geared. i know what i’m getting my LS right now…
He’s just saying you can compare rpm/mph readings from the short geared YS1 transmissions (given all else is equal) and see if they match yours. Not to take yours out and count the teeth.
Overall longer gearing of the LS should give better mpg but there are many other factors than just transmissions that can affect one’s mpg, such as driving style, tires, brakes dragging, engine condition, and so on…
I don’t mind going 60 and get passed up by almost everyone on the highway because 91+ octane isn’t cheap 
Also the YS1 code won’t tell you whether it is a long gear or short gear. I’ve heard plenty of stories when people were told they were buying a short geared transmission because it was a “YS1” but it ended up being a long geared LS.
My advice if you wanted a for sure short geared transmission is to purchase a OBD-0 JDM B16 J1 or S1 but then you have to worry about the condition, synchros, and so on… OR do the type-r swap into a YS1 case!
I’ve researched our transmission options and its a headache with never ending options and factors. I just hope my current transmission will last another 100k (currently has 195k with no work).
i know all of that…i was trying to gather information on who has what transmission and what MPG/Miles Per Tank they were getting. I’ll do research. i forgot where i found out how to tell which YS trans is short and long. it’s been so long ago, at least 6-7 years
just in case this thread is searched, here’s a link i found via search engine on here:

My mistake for misinterpreting what you were saying… Your first post implied that you have a YS1 and want to know what to replace it with…
You then asked how to tell if a YS1 trans is short or long… I figured you meant your CURRENT transmission, so I said the easiest way to do that…
Yes, you open the case and count the final drive/ring gear teeth, along with the other gears, to find out which trans is which.
