Default 04 Wrangler Unlimited Auto trans Shifting Issues

having a problem with my 04 wranger unlimited auto trans.

When going up steeper hills on the freeway at 65mph (OD on) my engine
starts to bog and shudder a little and hte transmission doesn't
downshift under standard gas pedal pressure. But, if I step on it it
downshifts 2 gears and spikes the rpms. I usually have to manually
avoid this right now by clicking off the overdrive when I see a steeper
hill ahead. The tranny should do this automatically when it dips into
the lower rpms.

Any thoughts? Does anyone know if there was a shift point update for
this tranny?

Thanks - Dustin

First things first, check the fluid level.

Have you recently upgraded to larger tires or added weighty mods to it - any
such thing?
How many miles onit? Have you had the tranny flushed and the filter changed?

Been through any deep water lately?

Mine did that to some degree, shifted like a pig until I put 5:13 gears in
it.
It's like night and day, and I can even pass without waiting for a downhill
slope.
I gained 20% on my MPG too!

That is good to know about the mileage. I wonder if I could get 30 mpg if I
put 5:13 gears in my four cylinder Jeep? ;^)

I have an 05 rubicon with stock 411(0) gearing. Mine acts just like
yours in even the slightest hill/grade. Its quite pathetic actually.
Of course, I have heavy bumpers, and running 33's, with a winch, all
heavy garb, cargo cage, etc.

I think I will go the route that Kate did. Only I think I will go to
4.88.

Manufacturers have been doing this for years, putting lower than reasonable
gear ratios in new vehicles so that people think that they are getting
better economy. The engine is turning slower, so I must be getting better
mileage, right? When I worked in the Dodge dealer in 1978 we would see
passenger cars with really low gear ratios and terrible mileage, and we were
supposed to be in a fuel crisis. Put in a higher gear ratio, the car would
be able to get out of its own way, the mileage would improve every time, and
the customer would be happy.

Gene Berg, VW drag racer and engine builder, pointed out however that the
higher numbered gear ratios are weaker because of the small pinion gear.
Something to think about if you want to off road or two. Tanstaafl.

Cheers,

Earle

Hey Kate,

If I recall you had 33's right and an auto tranny right? What rpm are
you running at 65mph in OD? I am curious what your engine is cranking
with those low gears. Thank you!

I have the stock 30" goodyear tires with no lift and a hard top.
Pretty basic setup with no mods. 47,000 miles. No deep water lately.

Thanks so much for the tips. I will look into the different gearing
options. From what I've read, this year's axles has 3.73 gear ratio.
I don't do any rock crawling. Most of my wheelin involves snow or
dusty desert & mexico trails. And, I need to keep my freeway speed as
this is my daily driver.

Any recommendation on gearing given my wheeling style and a daily driver.

That's right, I have a 4sp auto, 33x12's.
At 55 I'm right on 2,000 rpm
at 65, 22-2300 rpm. It's smooth as silk now, and the fuel mileage has
improved 20%.

I'm running 33's, and I'll tell ya, I strongly recommend the 5:13's.
If you ever go to 35's, you won't regret it a bit. I plan to go to 35's when
these wear out.
