festiva 4 speed auto conversion

[Bert]

Imperial gallon is 4.54 litres
US gallon is 3.78 litres

You Americans retained the old British measure of their 'gallon/quart/pint' when you became a Republic. The Brits on the other hand revised and standardized that version of the gallon in the early 1800s. Hence the difference. Most Commonwealth countries used the Imperial gallon until metric measure was invoked (in our case in about 1978). Ya gotta be becoming an old duffer (or be a Brit) to still understand volume in Imp. gallons. Just like I've entirely lost touch with miles per hour over the past 35 years, and dimly remember Fahrenheit temperatures.

Here is the new/reman torque converters available now through transtar / recon. Sure would like to know what the paint
codes mean. There are no lock up converters available anymore, they say non-lockup or lock-up omitted.

Note that the F4A transmissions can get lock-up with either a high or low stall torque converter. Is this F4A the BF
chassis transmission??

Bert, yes it is unusual to burn so much fuel for a 1300 injected engine, 3 speed auto. And yes it is in 3rd gear @ 2200 or is 2300 rpm
It's now got to get done by workshop with all this new age stuff for checking things.
It runs well though, starts ok, drives well etc.
I'll do process of eliminations over the next few days and see what happens.
Thanks all.

[FestYboy]

Filled with fuel today, numbers are, 30.8 litres at 310 kilometres.
Has power steering, air/con and mainly city driving.
Is this the average fuel usage for this model car or is better expected?
Thanks.

that's what Caety gets out of her 96, and she has the same options and all she does is city driving.

[FestYboy]

Man 10 l/100k, that's like a V8 for mileage. I easily get 500k on 30 litres (and that's in the cold with snow tires). In summer with a soft foot I can get 5.4 litres/100k which is roughly double efficient to your run of bad luck. Now this a 5 speed we're talking about but autos aren't radically much different. I think you have an air leak or a VAF problem (vane airflow sensor) that is causing the ECU to read funny or not properly. I didn't check back on your tune-up list of posts but a new oxygen sensor sometimes makes a substantial difference. Newer Aspires had 2 of these whereas Festys and early model Aspires only had one.
For sure you'll want to get to the bottom of this and fast.

autos are radicaly different in the rpms and mpg vs. a 5 speed car. also, the aspire runs a MAF (hot wire) system. the second o2 sensor on the 96-97 aspires is there to monitor the efficiency of the cat ONLY (has nothing to do with A/F control). i can also double Caetys milage with my 5spd Aspire vs. her auto and i beat the snot out of it.

i would bet that if the TC was swapped out for one WITHOUT lockup, he'd see an immediate 5-8 mpg (similar milage to what i get out of Pepe, my 91 auto around town).

[Movin]

I think you are right ^^^ the drive train was designed from the beginning for a manual transmission.
Auto's were a limited add on and re-engineering the whole system for best performance and mileage
was not done..hook it up and make it pass EPA!

Ok...for us US guys....can you do the math for us or me and tell me what the MPG are for your Auto and your 5 speed..

Well considering the US is one of the few countries left using the imperial system, shouldn't YOU do the conversion? :p :lol:

[fezzy]

Convert to 5 speed manual me thinks,

[Bert]

Ok...for us US guys....can you do the math for us or me and tell me what the MPG are for your Auto and your 5 speed..

Best I could ever get out of the auto was 45 mpg (Imperial) and 2 years ago I actually managed to cross the 50mpg (Imperial) barrier with a 5 speed. Seeing as 3.8 litres (US gallon) as opposed to 4.5 (Imp) differs by about 3/4 litre I think it is safe to reduce my numbers by that percentage. I can retrieve my gas log books if this really interests you. I've kept gas and mileage records for all my vehicles since 1978. Last year I retrofit a 3.00:1 Ford 9" axle into my straight six 86 F150 and also installed a 5 speed OD; speedo read 20% low right after that but the extra gear didn't turn the old girl into a slug. Got 26 mpg out of it on the highway during the summer and this with a tall canopy and roof racks on board. I use a GPS unit to calibrate the speedo and odometer, in case you're wondering.

In the US, the non-electronic 4 speed (designated G4A-HL) was only in the '88-'89 323s, and only available on the hatchbacks and sedans. But not all the hatchbacks and sedans even had it. Quickest visual cues to it being the 4 speed is an "O/D off" button on the floor shifter, and under the hood there is a black front cover on the trans that runs vertical, and a regular oil pan on the bottom. On the 3 speeds, there is just one pan and it its at an angle, same as the festiva trans.

I have a 4 speed auto (which also has lockup) in my basement. Should give the same cruising RPMs on the highway as a 5 speed manual, at least going by the numbers. Biggest issue is that its BIG. Axles should not be a problem, should be able to use the axles from an auto 323. Instead of a vacuum line to the intake manifold, this trans is controlled by a cable that runs to the throttle body. So if you get one from a yard, make sure you get that cable and bracket too.

If I could wrap my head around it I would....lol I am good at math but always hated word problems.

If you have the ability to do the math....please do. I want to know what you are getting with an auto Festy in US MPG.

Or if anyone else can just tell me...please do....from the numbers I am seeing and guessing at...I do not see how it is getting the milage it is.

[bhazard]

Re: festiva 4 speed auto conversion

I've never seen better than 36 us MPG from an auto festy. Its crazy.

[GenevaDirt]

thats what I am saying...I have seen 36 one time....but that was once on a trip for summer Ohiostiva.

[crazyrog17]

My auto gets around 27mpg in town. That's also if I'm driving in grandpa launch mode and staying under 50. I did see almost 30 on the way home from ohiostiva, most of the way was 60mph. On a regular day, I'm driving like an idiot and getting mid 20s. Still, that's way better than the 15 mpg I was seeing in the Grand Marquis.
