help! jeep broke down

[corbas]

my dads jeep broke down. hes on camel back 16th street and needs to get it to chandler. transmition problem. can anyone help? 480.235.2796

[corbas]

Had my daughter post that while I sat in the Jeep I've had for 1 %$@&*# month! Wouldn't shift out of 1st and was acellerating like a dump truck. Hopefully something easy:rolleyes: . Sound familiar to anyone?

[ademster]

is that the asian 5 speed trany... like the pugout or something like that.


probably the teflon pads on the shift forks worn out completely or broke off..

[corbas]

No, 4.0 auto.

[ademster]

Check your fluid level
is it burnt? Brown?

[corbas]

Still clear. No leaks.

[ademster]

is ther enough in the tranny... how did you check the fluid?

[David C]

If you are still under 70K miles, I think it would still be under warranty.

[corbas]

Checked while running in park.

[corbas]

66,000. Would it be covered with all the aftermarket goodies? (lift, gears, etc.). I thought of that, but figured that would be too good to be true.

[ademster]

Well... sounds like either you pump had taken a dump or... your pump isnt getting the proper flow of fluid due to the pick up screen being gummed up...

or one of the speed sensors have failed... or tps sensor failed...

check engine light on? what were you doing or what ever when it failed.

We have the same problem on a friends 97 4.0 auto, it will **** but not till about 4K rpm. We have a friend that works trannies and he swears its the valve body inside where the filter is. He has a machine that electronically checks things and he said the rest cecks good, maybe the same problem

[corbas]

Hoping it's just a screen or sensor. Engine light has been on for weeks for an emissions leak. Took it over 4000 rpm, no shiftie. Had a call a little bit ago from someone here who sounds like he knows what he's talking about. He said check the cable to the tb and a fuse. Gonna check that before the shop touches it. I figure the more info I get here the less chance they will try to pull one over on me.

[corbas]

BTW, I greatly appreciate all the help and education I have recieved from this site. It has proven to be an excellent tool for anyone with a Jeep (except mallcrawlers :D ).

[ademster]

try this

1. Remove the transmission relay and attempt to shift the transmission manually. If it shifts during this test, the transmission is likely OK, the problem may be electronic in nature.

2. If the transmission shifted normally in the first step, then monitor the governor pressure and the sensor voltage while driving. Normal values are as follows: Speed, Pressure, Sensor Voltage: 0 MPH, 0 PSI, 0.67V. 10 MPH, 2 PSI, 0.70V. 20 MPH, 13 PSI, 1.13V. 30 MPH, 25 PSI, 1.62V. 40 MPH, 37 PSI, 2.24V. 50 MPH, 52 PSI, 2.63V. 60 MPH, 59 PSI, 3.01V.

3. If the pressures are erratic, but the pressure sensor seems to be reacting to the pressures, then it is likely the governor pressure solenoid may be at fault. Always verify the fluid condition and check for clutch material in the pan before replacing the solenoid. If it is excessive, then rebuild or replace the transmission.

checking something right now, but first question is on fluid checking.... I believe is supposed to be checked in neutral (when in park, bypass detent causes high (2-3qts) reading)
read dipstick ("check in neutral with engine running")

[ademster]

also from what I am reading the governor pressure sensor has caused this paticular problem .....

test:

1. Check the voltage of the governor pressure sensor with Key On Engine Off (KOEO). It should be about 0.5 volts.

2. If the voltage is over 0.8 volts, check if the transmission temperature sensor is reading accurately. If not, check the sensor ground at the sensor.

3. If it is OK, replace the governor pressure sensor.

STANDARD PROCEDURE - TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:


Start and run engine at normal curb idle speed.
Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and leave engine running at curb idle speed.
Remove funnel, insert dipstick and check fluid level. If level is low, add fluid to bring level to MIN mark on dipstick. Check to see if the oil level is equal on both sides of the dipstick. If one side is noticeably higher than the other, the dipstick has picked up some oil from the dipstick tube. Allow the oil to drain down the dipstick tube and re-check.
Drive vehicle until transmission fluid is at normal operating temperature.
With the engine running at curb idle speed, the gear selector in NEUTRAL, and the parking brake applied, check the transmission fluid level. CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.
Add fluid to bring level up to MAX arrow mark. When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.






Effects of Incorrect Fluid Level
DIAGNOSIS AND TESTING - EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid pressures to be low and develop slower than normal. If the transmission is overfilled, the gears churn the fluid into foam. This aerates the fluid and causing the same conditions occurring with a low level. In either case, air bubbles cause fluid overheating, oxidation and varnish buildup which interferes with valve and clutch operation. Foaming also causes fluid expansion which can result in fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be mistaken for a leak if inspection is not careful.

Are you the 2nd owner of this Jeep???? If so you may qualify for the 7/70 powertrain warranty. I can check the last 8 of the VIN in our system tommorrow morning.

You're creepy. I was just going to ask you specifically about the warranty, and there you are.

3rd owner I believe. I can get the vin in the morning, but 3rd owner probably disqualifies me, huh?

[amber.hodge]

I just saw this thread. I hope everything turns out alright. Not fun to have a broken jeep, but if you're going to have one, this forum is the place to be. :)

[offroadaz]

I brought mine in lifted with aftermarket parts on it at 52,000 miles and they replaced my transmission with no problems when it went out

3 of my friends all have 2001+ 4.0 autos and all of us have had to replace or rebuild the transmission around 40,000 - 70,000 miles

last 8 #'s: 3P369269. Might be internal, so I need warranty if I can. Thanks.

[corbas]

Just got off the phone w/ Earnhardt jeep - It's covered and there on the way to get it. Yay me!

Did I scare you???

3rd owner does if its a factory 7/70

Sorry I was busy selling today;) Glad to hear everything is ok....

Thanks for the help everyone. Leaving town for a few days in the morning, so hopefully I will be back on the road on Mon.!
