3.3L Grand Voyager shift point and rev limiter.

Can anyone tell me what is the shift point for the auto transmission on a
3.3L Grand Voyager when you floor it? Mine seems to shift up at around 5,000
rpm. Also, when should the rev limiter cut in? Mine cuts in at around 5,300,
well before the 6,000 rpm red line!

Why, on earth, would you be beating your Grand Voyager, that way??
Why would these answers be important?? How OLD are you??

You still miss the point. Either the car is working as Chrysler designed it
or it is not. If you are prepared to drive a vehicle that is not performing
to it's maker's specifications then that is a reflection on you. All my
question was aimed as was finding out was whether or not that was normal for
a Voyager. However, it would seem to be too intelligent a question for you
as all you can do is respond with insults! How I drive my car is my choice,
I don't ask you how you drive yours and frankly, I don't care. Now, either
respond sensibly to my question or not at all. Mind you, going by your two
earlier efforts, I may be waiting a long time for a sensible and dare I say
it "adult" response.

thats the way d.c likes it before red line
like the new hemi trucks and the electronic throttle it has it's limits for a
reason
cut down on warranty claims

 

Mic

Thanks for your response. It makes you wonder about the design and
manufacture of an engine which has to be limited to such an extent to reduce
warranty claims. Christ, my diesel Toyota Estima (Japanese version of the
Previa) used to rev more convincingly than this (until it was stolen that
is!). At least it had an honest red line (5,500) at which the rev limiter
cut in, and this is on a 2.2L turbo-diesel.

I have the 3.3 in a '97 Grand. The shift point is usually around 5100RPM at
full throttle acceleration...which always seemed early to me since the
engine hardly sounds like it's working very hard yet. I have no idea when
the rev limiter would kick in...I don't even know what one would do to find
out. I can't figure out why it matters. Are you having drivability
problems?

Chrysler warranty is 100,000 miles, Toyota is 36,000 miles. That may be
more of the reason. If setting shift points lower saves your engine,
perhaps that is a good thing. How often does one ever need to run out the
engine at full throttle anyway? I can't remember the last time I even had
mine over 3000 RPM, let alone 5000!

I would respectfully say that I think you're running your engines way to
hard for this to matter. It's going to cost you dearly over time.

Be very careful, Matt. You might upset the pooooooooor widdo

He says he's waiting for me to respond in an "adult manner." I
plan on letting him cool his heels about four years, . . . . or until he can
vote, which ever comes first.

Some sanity at last! I was of the same opinion i.e. it seems to shift very
early while it shows no sign of rev related stress. By the way in the UK the
warranty is not 100,000 miles but considerably less, more like a limited
warranty of three years or 60,000 miles. With regards to the use of full
throttle, I agree, it is only on the rare occasion that one has to use full
throttle but on those occasions it just struck me as strange why it changed
so early in full kickdown mode. But on the other hand, a V6 is full song is
quite an addictive sound. As for the rev limit, it was just by chance that I
found that one out! However, the tacho red line is 6,000 rpm, this would
seem to be decoration only as is bears no relation to what the engine is
actually constrained to. As for the responses from two of the other
contributors, I am afraid that we do really have kids amongst us.On the
other hand, perhaps the sight of (WOW) 6,000rpm red line is for their
benefit. Personally, having had various cars and motorcycles over the past
thirty plus years, most of them being of European and Japanese origins, I
have grown accustomed to relatively high revving engines and realistic RPM
limits. In overall terms I expect honesty from car manufacturers. I also
expect, on the rare occasion, to be able to extract maximum performance from
the vehicle, which, if it has been designed and built correctly, will have
no effect on it's longevity.

I've never felt as though the engine was holding back for power though.
Maybe Chrysler heeds to offer the "auto-stick" tranny in Caravans for the
folks that want to hit that torque curve just right!

 

Karl / Matt

Unfortunately, although the best thing is probably to ignore the incessant
drivel put forward by both you and Matt, the temptation is just too much to
resist. The posts that the two of you have made really lower the tone of
this group. It perhaps brings it home to me why I generally refrain from
posting, there are too many ***ho*** out there who would rather play with
themselves and exchange frankly rather infantile posts. It is a shame that
the few can spoil it for the many.


Gerald

 

If you want "maximum performance" from time to time, fine. But being
able to tag the redline doesn't give maximum performance. Redline is
typically a mechanical limit at which the probability (note that word:
its not a certainty) of engine damage begins to rapidly increase with
increasing RPM. But redline is rarely the peak horsepower RPM, and is
virtually NEVER the peak torque RPM. It is generally well above both of
those and torque certainly has begun to fall off before redline and
horsepower is either flat or also on the downward trend.

Maximum performance during an upshift is really determined by where on
the torque curve the *next* gear ratio causes the engine to wind up
after the shift. You might sacrifice a little bit in the lower gear by
going above the horsepower peak before shifting in order to not end up
being too far on the low side of the torque peak in the higher gear, but
that usually doesn't entail going all the way to redline. That is even
more true of an engine like a 3.3L that is set up for low RPM torque
performance rather than high RPM horsepower performance. The automatic
WOT shift points are most likely very near the absolute best for that
engine and transmission combo, because revving any higher justs puts you
further on the down-side of the curve. And I do think that 6000 is
probably a realistic redline for that engine, the 3.5 has a 6500 RPM
redline, and shares much of the rotating assembly design with the 3.3,
but has lighter pistons and a forged crank with cross-bolted mains. Both
could probably hit 7000 and only a small percentage of the engines that
have been made would suffer immediate damage, but a more conservative
redline makes sense.

And finally, engine sound is not any indicator of "rev related stress"
at all. Some engines make incredibly loud noises with no stress at all,
and others will remain "normal" sounding right up to the point where the
rods make windows in the block. I'm *certain* the 3.3 is under
absolutely no abnormal "stress" at all at its shift point, I'm just
pointing out that its not a good idea to judge by sound alone.

Good response. Further research reveals the following:-

Max. output
(DIN) 152.1 PS (150.0 bhp) (111.9 kW)
@4850 rpm
Max. torque
(DIN) 241.0 Nm (178 lbft) (24.6 kgm)
@3750 rpm


Funny that after owning the thing for three years I've only just looked up
the specifications!
All in all it is an understressed, low output engine, 150HP out of a 3.3
litre engine (their own 2.0 litre engine apparently produces 140bhp) is
nothing to get excited about, neither to be honest is 178 lbft. In
comparison, my (albeit tweaked) 1.8 litre 8v Golf GTI produced approximately
140 HP at 5,900rpm and approximately 140 lbft of torque at 4,300rpm and had
178,000 miles on the clock when I sold it (expanding family). But of course
we are talking about an engine with completely different design parameters.
I have no doubt that 6,000 is a realistic red line for the Chrysler engine,
in fact 5,800 is probably a safer bet. I was just puzzled that with 6,000
apparently available RPM, this one short shifts at just over 5,000 and would
never ever reach that 6,000 mark in a month of Sundays because the rev
limiter cuts in at about 5,300! But on reflection, the specifications say it
all. I do know all about horsepower and torque curves and have been working
with engines for some twenty years now. As such I agree that sound alone is
no good indicator, however sound and feel combined with a much higher
indicated limit does prompt for some questions to be asked. Again thanks for
your measured response.


Gerald

 

The torque curve peak is nowhere near the redline on almost any gasoline
four-stroke. Some diesels may come close, but most gasoline engines
have the torque curve well below redline. The horsepower peak is often
much closer to redline.


Matt

 

When you grow up a little more, you will find it easier to resist these
urges to respond. And your IQ will, hopefully, rise to a level that
allows you to express yourself without profanity.
