Question about 1990 Mazda MX-5

1 Answer

1st to 2nd problem with MX5

Cheers for that, I have not had the car very long. I spoke with an auto trans repairer here in Rotorua who suggested it was a pressure valve problem and that a simple solution was to drill a hole in the part of the trans which would relieve the pressure. After your comment I am unsure now whether to trust his judgement. Where would I make the adjustment you suggest?

Thank you again
Ian

Hi Ian,

Considering the advice I got many moons ago from a very respected transmission specialist to never even change fluid unless it smelled burned because opening that closed system was inviting disaster, drilling a hole in it sounds especially repugnant. Producing drilling chips inside and then leaving a breathing hole sounds insane.
Clearances and valveing inside the things is extremely critical and a speck of anything can disable the beasts.

I cannot advise you on the specifics of your tranny as they may even vary from one market to another.
I looked to see if NZ had a chain similar to those we have in the US and it appears that Repco might be the right choice to check for service manuals that should be oriented to your market.
I recommend to all that they should have one in their car in case you are far from home and need service in an area that might not have the info they need to get you rolling again.
I suspect Haynes manuals should be available (they were once a British publisher, now acquired by Chilton) in your area and they are well written.

1994 Ford Escort, auto trans, 83,000 mi, randomly won't shift from 1st to 2nd, randomly loses power at hwy speeds


It could be an internal problem with a pump, or it could be it needs to be serviced really bad. Most 'oil change' places can also do transmission services... I'd try that first, before paying a big repair bill to a shop. good luck.

1999 DODG 3500 AUTO TRANS SHIFTS TO 2ND WITH A LITTLE HELP


I have a 1999 Ram B 1500 Van, auto transmission, 5.9 L engine.
Same problem, trans hesitates in 2-3 upshift, sometimes 1-2
to 2-3 upshift. Posts trouble code P1756 - Transmission Govenor pressure too low at below 15 to 20 Psi. Transmission pump shot or valve body leak stops trans from reaching proper pressure to shift, which is minimum 15 Psi.
Either trans is leaking in valve body, valve is stuck, shift solenoid on valve body is sticking, or pump is shot.

I have a E36 328i *** import. When cold the shift from 1st to 2nd is extreamly rough. After a few km's (possibly when the trans warms up) the shifting is perfect. The problem only occurs between 1st &...


I had the same problem with my car it is not a major problem your car probably has high mileage, You can replace your torque converter replaced but that will be expensive, The price to fix it completely outweigh's the problem.

What I suggest and works for me is while the trans is still cold just anticipate the shift from 1st to 2nd and just before the change occurs eas of the accelerator and then when the car has changed from 1st to 2nd just accelerate again.

Honda accord exr 1987 automatic trans.


It's hard to understand when you say it feels like a manual shift. Noise? Feel? I do know that the 87 auto trans does have a weak 1st to 2nd shift drum (as explained to me by my mechanic) that makes a grinding, elongated shift under heavy acceleration when it starts to wear. Under normal acceleration, 1st to 2nd shifts were normal (crisp, immediate). Since that day 8 years ago, I've avoided starting off to quickly, and so far have saved myself a tranny overhaul.
