The code P0731 means incorrect 1st gear ratio, it is applicable to automatic transaxle only. To troubleshoot, check shift solenoids #1 and #2.

how to access trouble codes and question by john32626

I have a 95 626 2.0L, 5 speed
I'd like to know how to access the trouble codes stored in the computer.
is there a cable and software that I could plug the car into a laptop with?
 
ok now the question of the day...
193,000 miles, at idle the engine runs a bit rough, new NGK plugs installed and didn't help. think it may be ICS? has a vibration at 1500 rpm in neutral, oscillating somewhere.... harmonic balancer?
 
This is the first small car I've ever owned, I love it so far, but I really am not used to dealing with computer controlled cars. sometimes I wonder if I've got the rubber band wound too tight.. LOL
 
thanks for any help ya'll can give...

my car wouldn't go more than 20mph so the mechanic told me to change the piston rings after he did a compression check the number 3 piston wasn't working so i replaced the piston rings, had the head redone, replaced the headgasket, did a full tune up, but when i went to turn it on the car doesn't start. I believe 100% that it's the timing but i'm a bit rusty at it can someone help me please?

Tranny problem on 95 626 by guidry3

Does anyone make a after market cooler for the tranny. I think the main problem
with the trans of this era is they are too small for the weight of the car causing
them to overheat.

Mazda 626 LX 1999 Model - Screeching noise from belt by saeedabidi

My car make screeching noise when it is cold and when you start the car in the morning. The noise comes from the belt. I used belt spray for a while, which makes the noise go away for a day but keep coming back the next day.
 
Is there a permanent and cheaper solution to resolving this noise from belt.
 
Thanks

Several aftermarket coolers will fit; you want a small one with sandwich-plate design (looks like a smallish radiator) that plumbs into the existing fluid lines and fits in front of the radiator.
 
Mazda at one time had a factory kit for these things, but it was pricey.

No sorry the "belt dressing" doesn't really work very well. You can try tightening the belt up a bit but if it is glazed from slipping you have no other choice but to replace it. But check the tightness by all means.

Do you think the main problem with these trans is overheating and what are the
chances that this will fix the problem after it is rebuilt?

That's always been my impression. There were some design flaws early on, but most of them had been corrected by 1999 or 2000, and replacement parts have followed the newer, less fragile designs.
