Hello everyone

I just bought a 2006 mazda5 with 97k on it.
I have read that the 2008 got upgraded to a 5 speed auto tranny.
Will the 5 speed auto out of a 2008 work in my 2006.
It would be nice to have that extra gear and most likey save money highway cruzing to.

 

If the engine is the same then it should fit but the cost to replace your computer, tranny, CV axles and possibly the front hubs/brakes makes it not worth the savings in fuel you would save, your talking thousands just to change your transmission. Best way to save fuel is to drive on the highway/freeway at 50-55mph that is where the majority of cars get the best mileage, my truck gets its best at 45-50.

 

Spend $5,000 on a tranny to save A few hundred a year! LOL

at least wait til your tranny goes. I guess your planning ahead, sorry, couldn't resist!

 

@UYN LOL yes i was driving late last night on the highway staring at the tack @3000 rpm thinking man it would be nice to be down around 2400.... so yes I more thinking ahead if i have tranny problems. Witch a had in 2 of my 3 626's but they where all 150k+

 

My tranny blew @ 35,000 km! Well almost blew. Clunked real hard and was changed under warranty. Since the new one i have installed an external tranny cooler and synthetic oil. So far so good but only a total of 58,500 km.

A 4 cylinder is suppose to rev a bit higher than 6 cylinder, it's the nature of the beast.

 

Almost all 4 cylinders get their best fuel economy at around 3K cruising, my 3 hates being under 2500rpms and guzzles fuel, above 4500 and it also guzzles fuel. The more low end power or torque you have the lower your cruising RPM can be due to there being sufficient power at that RPM to move the vehicle. Most 4 cylinders today have peaky high strung HP and torque curves so higher RPMs are better in their case.

 

I haven't driven a 4 daily since 2005 my other car is a Alero with a v6 3400 lots of low end... guess i just have to get use to it again.
