I too have a 2005 Mazda MPV, with low miles, around 37k. I have it in the shop today, as there appears to be an odd transmission slip. Seems that when shifting around the speed of 40, the van sometimes does not want to shift up in gear. More gas just displays a higher RPM range on the tachometer but does not produce any higher speeds. It seems to want to get into gear but can not at times. Reducing speed seems to allow it to get in gear but this is not normal. This did seem to throw an engine light/code that is unknown to me, as of the moment. This all happened, just today and has never done this in the past. Let's see what the dealership states.
Considering the mileage on this car and the posts I have read thus far, it certainly sounds like there is an engineering opps from Mazda/Ford here.
I am now an un-happy Mazda owner. Nobody should see issues with a car under 50,000 miles.

or maybe a only time will tell.

Anyone have any insight to this issue
How often do you check your trans. fluid? Have you had it flushed yet?
My 2004LX with 70k miles had trans fluid looking dirty at around 23k miles. Had it flushed then, and again around 50k miles. If not flushed may have been a contributing factor in current problem.
#154 of 191 2002 MVP made it to 107,000 before tranny gave out

Had a 2002 LX that experienced much of the tranny issues documented in this thread. Had it reflashed back when it was new. Kept up with maintenance. It still experienced hard shifts periodically, but it kept going until...
We were on a trip in the NC mountains in April and I had the cruise control set while on the highway. When we hit the first grade that required a downshift from OD the tach took off toward redline! We were able to complete the trip, but any time that downshift occurred it was nothing but slippage.
Had it checked by our local mechanic. No codes plus that slippage = shot trans. Estimate for installing rebuilt was ~ $3,500 (more than the vehicle is worth).
Another MPV bites the dust...

Wow, you've been a member for 9 years and this is your first post?
The rebuild price is a lot better than some others I've seen. What other repairs/issues have you had? If you can get a good warranty for the trans repair, may be worth taking a second look.
Also, I don't care to use the cruise control much, the thing has a heavy lead foot and will accelerate too hard. Probably not a good idea to use in the mountains.
#156 of 191 Changed Gas
Jun 01, 2010 (5:29 pm)
My Mazda 2003 van's transmission began slipping from 2nd to 3rd and then would catch with a thud. The transmission people said a rebuild would be $2400 to $2800. By chance I filled up with a tank of gas without ethanol. It quit. I filled up with with my regular gas with ethanol, it started again. I have been ethanol free, and problem free, for a couple of months now.
I'm not a car guy nor do I have issues with ethanol. It may be a coincidence.
For what it's worth.
#157 of 191 Engine vibration in 2003 MPV - transmission related?
Jun 13, 2010 (12:16 pm)
We have noticed engine vibration when our 2003 MPV (158k kms or ~ 100k miles) is idling at traffic lights or at the parking lot. Vibration would get stronger with longer idling time and the whole van will be shaking.
Took it to the local Canadian Tire store (we are from London, Ontario, Canada) and the techs could not read any codes from the van's computer. Either the van's computer is not working properly or the sensors are not sending out any fault codes.
They replaced the spark plugs and did the engine flush, but the vibration is still there and the tech can feel it while driving. Now they think that the pulley (where timing belt is) is cracked and is going to replace the pulley and the sensor behind the pulley. They are not sure whether this will solve the problem.
Because they cannot read the codes, they are guessing and changing parts they think causing the vibration problem. I did the engine tune up only last month and hence not sure what is the real cause of the vibration issue.
Could this be related to the transmission slowly fading away?
Any help you can provide will be greatly appreciated.
Thanks so much,

a typical suspect for this symptom (engine running rough) is one of the coils (one on each spark plug) and/or the PCV hose. Both will cause a rough idle, sometimes less noticeable than other times too. And most often it won't trigger a CEL, seems it has to be pretty major to do so, or after impacting one of the O2 sensors.
Check your plugs, wires, and coils, and the PCV hose. While you're at it, check the MAF and IAC and inspect the air box tubing. Typically the rear bank of coils are more prone to act up, but all are fair game.

Thanks so much Brian. I need to replace the cracked pulley first and, if the problem still persists, I will ask the mechanic to check the the PCV hose and the coils. We have recently replaced the spark plugs and my mechanic tells me that IAC may not be the issue. MAF also needs to be looked into.
Thanks again, Sridhar.

I'd say the idle air control valve. It's an easy do it yourself... sits right on top ($50).
I probaby wouldn't be taking my MPV into a tire store for repairs. Doesn't sound like they know what they are doing.
#161 of 191 Transmission Problems After Battery Replacement
Jun 14, 2010 (11:07 am)
I have a 2002 Mazda MPV (bought used about 18 months ago) and I just got the dreaded hard shifts that feels like someone rear ended me (unfortunately, I have been rear-ended a couple times in my driving career).
It's back in the same shop that my wife had taken the van to replace the battery. I would have replaced the battery myself but I had to work and she needed the car before I got back from work. It seems strange to me that a battery replacement would be the cause of this transmission problem. Even if the computer needs to reset and adjust, it shouldn't be THAT hard of a shift. The hard shifts happen between 1st and 2nd (hardest shift), 2nd and 3rd, and 3rd and 4th (this one feels like a hard down shift followed immediately by a moderately hard up shift). I didn't check 4th to 5th as the first several were enough for me to take it immediately back to the shop.
My wife originally wanted to keep it at the shop since the transmission acted up the moment she went to drive it out of the shop parking lot but the technician said it was okay and that it would go back to normal after a short bit. Well, it didn't go back to normal in the 2 miles I drove it from my house, the gas station, and then back to the shop.
Is this the end of the transmission? Or did I not "wait" long enough for the "computer to reset/adjust"?
EDIT: The O/D Off light flashes continuously even after I try to turn it off. According to the manual, it's an electrical/transmission problem of some sort. The shop hasn't called back to tell me what codes turned up if any.
