Ford Ranger / B-Series :: 2002 - Trans Hesitates - Shakes At 65 - 70 MPH?
Apr 7, 2013
02 ranger 4.0 v6 auto has 110000 miles on it. at highway speeds 65-70mph feels like it strugles to shift, truck will shake and bounce some. when this happens rpm's jump from about 2200 to 3000-3200 after a little bouncing rpms drop to normal. issue seems to be the worst going up hill but will happen every time i hit 65-70. Also the truck will not bounce or shake with the OD turned off and seems to run fine this way.
tranny fluid/ filter just replaced with no change. new plugs and wires

Having a slight issue with my ranger. So I bought this truck out of a junkyard about a month ago, its a 94 4x4 with a 4.0 and a five speed. When I bought the truck the motor was blown so a few weeks ago i replaced it with a 4.0 from an aerostar van I had laying around. Right after I changed it the truck was running good with no issues, until a few days ago going to work the truck started hesitating going up a hill. Now the truck does it all the time, sitting at idle the truck runs smooth as silk, at half throttle it does it the worst but when you mash the peddle to the floor it clears up and runs good.
So far I've replaced the plugs, wires, coil pack, mass air sensor, throttle position sensor, and the fuel pressure regulator to try and fix it but nothing has worked. I've checked the fuel pressure it has 30 at idle and 40 with the vacuum hose pulled off of the regulator, I even taped the gauge to the windshield and went for a ride and there was no drop in pressure when it started acting up. a few other things i have done were plugged all the vacuum ports to rule out a leak, reset the computer and checked for codes. the only code that came up was 522. So I think my next step is going to be buy new oxygen sensors ? But my question is wouldn't the check engine light come on if it was an oxygen sensor ?

Problem: engine surging/hesitation, from idle to highway speeds. It will start and run fine, just hesitates/surges when gas is applied.
Before I pulled the codes, I tried seafoam in the gas tank, cleaned MAF sensor, cleaned throttle body, checked air filter, changed fuel filter, pulled/cleaned plugs, nothing worked.
Then today I finally used a scanner and pulled codes (my CEL doesn't work) and I got 157 and 158 MAF sensor fault, high and low voltage. I am reading about 6v on the C and D terminals of the MAF, I know that is much higher than normal, but what does that tell me? Why both high and low voltage readings? Just a bad sensor, or wherever that voltage comes from, ECM?
I also pulled 189 HEGO H02S sensor fault, unable to switch/lean during part throttle. What does that mean, just a bad O2 sensor?
Last I pulled a 542, fuel pump secondary circuit fault. Does that mean the fuel pump is bad or going bad?
More importantly, what should I troubleshoot first, would any of these codes cause my problem?

I have a 1999 Ford Ranger and every morning when I go out to start it, it really hesitates and doesn't want to run for a few minutes. once it's going it's fine I can shut it right off and it starts fine, and I can leave it all day from 9am to 6pm and start it again at 6pm and it doesn't hesitate, it fires right up.. it seems like it only happens over night..
When I hooked the code reader up, I get codes P0171 (too lean bank one) & P0174 (too lean bank two)
I also get for the I/M readiness status, that the
EVAP - NOT RDY,
O2S - NOT RDY,
HO2S - NOT RDY
Just want to say also that the shop I had put 2 oxygen sensors in not long ago.=

1997 2.3 5 Speed. My poor truck is having a hard time shifting into gears. I have bled the master off the truck with the correct method, bled it on the truck with the hose on the slave method while pushing the pedal and multiple times with no bubbles coming out at all, no leaks, etc.
Here's the breakdown -
- Clutch, slave cylinder and shifter bushings replaced about 3 years ago (everything has less than 7000 miles on it)
- While driving and pushing in the clutch, it clearly disengages, although quite a ways down.
- Only shifts hard while running. If I sit with it off with the clutch in, I can shift through all the gears with no effort whatsoever. At times while driving, it gets so hard to shift that it may become dangerous.
- Only things I haven't replaced are the master cylinder and the flywheel.
Should I just assume a bad master and just replace it? It's the original with 188,200 miles on it.
Forgot to mention there are times that when I am at a standstill trying to go into reverse, it grinds like the transmission is still engaged.

Today on my way to work my 1993 ford ranger would shift fine but would refuse to go over 35mph and shook pretty bad. I don't know where to start...

I have a 98 Ranger SuperCab XLT 4WD 4.0 Auto. Occasionally, especially when it has been sitting for more than 3 days, it shakes for maybe 30 seconds on startup. It smooths out gradually after that, maybe 15 sec. to normal smoothness. It seems like it is firing on all cylinders and is more like something out of balance.
Never does it when sits less than 2 days. When it happens, the longer it sits the worse it shakes.

My 1999 ford ranger, when started, shakes and then while i am driving. my check engine light is on and reads a #3 cylinder misfire. I have taken it somewhere to get it checked out and they can't figure out what is wrong with it. this problem only happens 50% of the time. I don't know what to do. Also just got a tune up.

My problem is wih my 1996 Ford Ranger XLT 6Cyl. 4.0L 2WD Recntly it started shaking violently in the rear as I drive down the road any road. Mainly slow to about 50MPH or slower, it just starts to shake really hard and then it stops then out of the blue it will do it again I thought it might be the back Drums maybe the shoes came apart and were catching but they are fine everything looks fine, could it be the gearbox on the axle? I don't know...

My 95 4.0 has had a periodic idle issue for quite a while. It seems it may be getting worse. Here is when it may only happen:
Vehicle is fully warm. I shut it off for about 1 hr or so and when I restart it, it shakes and misses in idle. It will idle fine after I drive it around or if I rev the engine for a while when still parked.
This never triggers the "check engine light". New fuel filter, plugs and wires.

i have a 1999 mazda troy lee b3000. The truck has a 3.0 flex fuel and 4r44e and when you go to drive it. turn the key engine fires up but the trans won't shift into gear. Here is the back story.Bought the truck brand new in 99 I'm the original owner it was a daily driver up until 2 years ago. the truck has over 300k miles and still ran great but the camshaft was starting to go. I was gona replace the cam but came across a killer deal on a new engine. picked up another 3.0 flex fuel with 50k miles. drove the truck into my garage removed the old engine installed the new engine. got in the truck turned the key and the new engine roared to life.
I went to put the truck into gear so i could get it out of the garage and go for a test drive and nothing. went to put it in drive and again nothing. no matter what gear its put in it doesn't move at this point i was confused and decided to quit for the night. That was in 2011 its now 2013 the truck has just sat there sense then. I've tried anything and everything even went as far as swapping transmissions and computers with no luck. I took the trans apart I don't know how many times can't find anything wrong with it.

I have a 98 Ranger, 4.0 automatic 4x4...I just replaced the upper and lower intake gaskets and after fumbling with the pug wires to finally get them in the right order, I suddenly find my OD light flashing off and on, and the tranny slamming into second, and once in top gear can feel the OD popping in and out? From my reading here it looks like a pretty common problem, but the solution isn't as clear...
The vehicle set for about 3 months while I healed up from a injury, and and was working just fine when I parked it...due to the blown lower intake gasket. I am thinking I have a vacuum line not connected or wrongly connected...or some kind of over looked item, but I can't spot anything...should I get a code reader and go from there...

I have a 98 XLT 4.0, auto trans with 109K miles and when it's really hot outside and it's been driven when I start back up and put it into drive it sometimes takes a while to go into gear. A friend says the transmission fluid doesn't look too good and it smells. Obviously I have a transmission problem but my question is would changing the fluid do any good at all? Since the tranny is bad what harm could it do? The fluid was never changed previously.

The problem I have is the truck won't move in o/d. If I put it in revers 1,and 2 it works. A little back ground. 4 years ago the trans went out of my 95 4.0 4x4, had it rebuilt so it has 0 miles on it. It got really cold that winter had lots of trouble getting the trans and torque converter lined up. motor went bad on me. A few months ago finally had some money to spend bought a 98 explorer sport with a 4.0 x code motor. the motor runs fine apart from an oil leak and an exhaust leak. the exhaust leak is no big deal I just haven't gotten the system tight yet.

I have a 99 Ranger 3.0L automatic, ext cab, 2 wheel drive. Door sticker show code "T" which I looked up as the 4R44E. The trans seems to be slipping in 1st and 2nd. Thought it was "reared shudder", from a "limited slip" differential but mine is not limited slip. just the regular 8.8 with 373 gears.
Wanting to know what if any options I have for buying a new / rebuilt tranny? I've seen where depending upon the year and motor, Ranger can have 4r44e, 4r55e, 5r55e, etc.

Daughter driving truck truck quits moving, I get there no drive and no reverse, has low and 2nd manually.
drive truck home, flush trans and cooler, road test all ok. this was 3 weeks ago.
This morning did it to here again, no drive and no reverse, she drove it home using manual low and 2nd.
I get in and when put into drive it feels like it tries but doesn't go all in, same with reverse. pulled it into low and vola I now have drive and reverse again
I'm thinking a we may have a bad or going bad shift solenoid. What I need to know is, is any of the solenoid valves on when in reverse are they the same as when in drive?

I have a 99 ranger 4x4 4.0 V6 with 200K miles..I just had the slave cylinder replaced and bled however, it is still hard to get into gear and when at a stop light with the clutch pedal pushed in all the way the truck tries to move forward as if its in gear. I took it back to the shop and the mechanic says that the hydraulic system is working as it should and the problem could only be the pilot bushing failing and causing the trans to partially engage. The clutch and previous slave cyl only had 25K before the slave cyl failed and started leaking!!

I'm having a little issue with shifting into first. Once in a while it simply will not go in, like you're pushing the shifter against a brick wall. If I turn off the truck and turn it back on, it works absolutely fine. I can shift into 2nd-5th no problem at all times. Is it just the shift linkage, or...? I'm not really sure where to start.
