I recently bought a 2001 Z71. The manual says when shifting from 2hi to
4Lo it's best to shift going 1 to 3 mph. Why? And you can shift from 2hi
to 4hi at any speed. It has the electronic transfer case.
I also own a 1989 Mazda B200i 4x4 with a manual transfer case. I would
never change over to 4/wheeldrive unless I was completely stopped.
you can shift from 2 hi to 4 hi while on the fly. moving into 4 low is an
enormous gearing transition, and just barely moving is about as fast as you
want to go. My truck requires that I am in neutral to move into 4 low,
though not sure if the newer ones require that. The slight bit of movement
makes it fall right into gear from my experience, where if I am completely
at a dead stop, I have to push it in/grind it in a bit (not a perfectly
smooth transition). That ever so slow crawl and it pops right in. I don't
know what the gearing in 4 lo is, but it is very low, so watch your RPM's.
On your vehicle, the system will not allow you to shift into 4lo
unless you are in neutral and either stopped, or going very slow.
2hi to 4hi uses a synchronizer just like the forward gears in a
manual trans, so it will shift in at any speed. Even with that
shift, it's best to be neither on or off the throttle while the
shift is happening.
sorry you are stuck with a mazda.
shifting at a slow speed allows the gears to mesh easier and does not hurt
if you were stopped(as in Mazda)
often the gear trying to mesh will hit right on top of the tooth in the box
and you will have to jerk it to move the gear so they will mesh.
buy american or you are part of the problem.
The Mazda is just a work truck or gravel road truck. Its a B2600i . I
have had the truck 5 years now and has been a good truck, runs great,
never any problems. Except when I first got it. The head cracked. You
never want to replace the head on a Mazda. The cheapest head I could
find was a rebuild one for $1800. No way I was going to pay that. I
lucked up and found another mazda that was totaled out from the back-in.
I bought the whole truck for $1500. Anyhow, after this one I will never
own a foreign made vechicle.
American even if it had some assembly done in Canada or a component or two
made in Mexico. People seem to forget that when they claim their Hondas or
Toyotas are "American". The Assembly of a vehicle is only about 25% of the
whole thing, there are so many designers, testers, project manager,
managers, etc that make up most of an company.
