i bought this 1995 bronco the other day to be my off road toy. being a bowtie guy "sorry just stating my automotive knowledge" i dont have much experience with ford transmissions. i drove this truck home and everything was fine. parked it in front of the house and went back out to take my wife for a drive and i had no forward gears. put it in reverse and the trans engages and wont move. tried to push the truck back in neutral and it wont budge. push it forward and it goes. checked the fluid not burnt and full. started the truck again put it in drive and nothing. put it in reverse and gave it some gas and i heard a small pop from the rear end and she drives backwards. put it back in drive and nothing. now here is the weird thing. if i put it in 4 low and in 1st i hear the trans engage and if i rev the engine it goes backwards. WTF??? it has the 5.8 but im not sure of the trans. the truck is completely stock never molested. still has the original stereo in it. i bought it from an old guy who only used 4x4 a couple of times.

any ideas?

oh i forgot to mention that i checked the return trans fluid lines check valve and its working fine and free. i did find that online in a forum somewhere.

i check it with the engine running on a flat surface. im not sure about the trans. can you give me an idea on what to look for to verify?

its the E4OD then i think its the planitery gear set but im hoping its something stupid like a vacuum line or valve body issue

you most likely have an e4od. Which is a mess. I have nothing else of use to include so good luck to you.

This is a long shot, but have you checked the gear selector? i had one that did all kinds of weird s%*! because it was missing one of the bolts on the selector shaft. Also check the linkage underneath. Just a thought.
Good luck.

You have an E4OD. Start with the basics pull codes!! (here (http://www.fordfuelinjection.com/?p=13)) do that first. Post back. I wonder if the shift solenoids are jacked up. You have a weird reverse so I don't think the filter fell out and into the pan. Pull codes and post back.

Do a search for adjust transmission, a ton of them come up. I think its one of the first two links...

Pull codes before adjusting the mlps. If you pull codes it can tell if the sensor needs adjusting.

The gear selector can come loose at the steering column. The linkage is also prone to coming apart. Just my $.02.

but for it to go backwards in 1st gear??? i am beginning to think my valve body is jacked up.

I'm thinking the same thing.

But pull those code! It can tell if the mlp is wacked up/not correct position.

yo. I agree with CATSNW on just doing the DIY Diagnostic Trouble Code (DTC) Testing first.

There are two types of Tests, Key On Engine Off (KOEO) & Key On Engine Running (KOER).

The Link provided goes to Ryan M's KOEO portion of the test; Ryan needs to include a Hot Link someday to the KOER portion which is @ http://www.fordfuelinjection.com/?p=94


The engine temperature must be greater than 50F (10C) to pass the KOEO Self-Test and greater than 180F (82C) to pass the KOER Self-Test.

Run it around to heat the engine up and try to shift thru all gears incl Reverse. Then turn off all accessories/lights, etc.

Make sure A/C is off and transmission is in Park (automatic)

Do Key On Engine Off (KOEO) portion first.

Look Codes up in my broncolinks.com site using the new Search function if in a hurry.

And Post em here according to:
KOEO
& KOER


--
Is the Transmission Control Indicator Light (TCIL) (overdrive off/on Button and LED on end of shifter stalk Blinking?

Is Check Engine Light (CEL) ON all the time?

It should light up briefly when first starting the Bronco.

yo,
Why?

The DIY Tests need only a paper clip or jumper wire; and maybe a helper to write the info down.

oh really? im going to look that up.

tried the paper clip test got code 86 shift soleniod circuit error and code 68 trans shift error.

yo,
Unfortunately the 95's have 3 digit DTCs

Try the two tests again

well i just did it 3 more times and it gives me code 11 3 times for system pass then the 86 and 68. so maybe im doing something wrong?

yo,
OK

Who knows what a previous owner(s) or shop did, such as a wiring/harnees or EEC swap..
So
KOEO = Key On Engine Off
CM = Continues Memory
KOER = Key On Engine Running

DTC 68 CM - Transmission recently overheated, or Transmission Oil Temperature (TOT) sensor was overheated or intermittently failed below 0.2 volts; due to a lean condition or vacuum leak, fuel filter, fuel pump, Intake Air Temp (IAT); (Air Charge Temperature [ACT] prior to 1992) Sensor/circuit (possibly grounded)

Transmission Oil Temperature Sensor (TOT) Overview & Wiring Diagram; "...The PCM monitors the voltage drop across a temperature sensitive thermistor. The PCM uses this information to determine transmission fluid temperature for adjustment of shift schedules & torque converter engagement schedules when the fluid is cold. Also used to adjust EPC pressure shift & torque converter schedules for temperature..."

Transmission Oil Temperature Sensor (TOT) Removal; "...It is located in da Pack between Converter Clutch Control (CCC) Solenoid & the Coast Clutch Solenoid. Once you remove the pan locate the sensor in the valve body and remove the electrical connector very carefully. The sensor is about the size of a pen cap. To remove the sensor carefully unlock the stop tab and twist it, pull down to remove it. It comes out before a full quarter turn is made. Put it back in the reverse order. When you get the sensor to come out be prepared to catch the trans fluid that follows behind it, you will get less than a quart out of it. It is located in da Pack between Converter Clutch Control (CCC) Solenoid & the Coast Clutch Solenoid. try the connections first. They are usually the root of the problem..."

Overview & Testing; "...This measures the temperature of the air entering the engine. Which impacts the fuel ratio; the cooler the incoming air is the denser it is. Denser air can utilize more fuel, giving us even greater accuracy in obtaining our desired air to fuel ratio. Before you start blaming the air charge temperature sensor and replacing it make sure the rest of the coolant system is in good condition.

==============
KEY ON ENGINE OFF
1. Hook up a VOM as shown in Quick Test.
2. DO NOT ground STI if using a VOM or "Check Engine" Light.
3. Turn the ignition key to the ON position.
4. You are now in the Continuous Monitor (CM) Mode.
5. Tap, Move and Wiggle the suspect sensor and/or harness. If a fault is detected, a Service Code will be stored in memory and will beindicated as explained previously
HOW TO CLEAR CONTINUOUS MEMORY CODES
1. Run the Key On Engine Off Self-Test according to Quick Test.
2. When the Service Codes begin to be displayed, deactivate Self-Test:
Disconnect the jumper wire from the Self-Test connector.
3. The continuous service codes will be erased from the processor's memory.
