Why is my Ford E-250 van shifting erratically or hunting for gears?

Short answer: On an E4OD van, erratic shifting or gear hunting is often a speed sensor problem, especially if the cruise control acts up too. If the O/D light flashes, have the codes read first. Then check the fluid and the TV cable adjustment. Burnt fluid points to internal wear.

Symptom: The transmission shifts at odd times, hunts between gears, flashes the O/D light, or the cruise control drops out.

What to check first

1. Have the transmission codes read. A flashing O/D light means one is stored.
2. Check the fluid level and smell with the engine running and warm.
3. Inspect the speed sensor and its connector.
4. Check the TV cable adjustment at the throttle.
5. Fix engine problems like misfires first, since they confuse the shifting.

Likely causes

1. Speed sensor. The transmission computer uses a vehicle speed sensor to decide when to shift. A bad sensor causes odd shifts and cruise control problems.
2. Transmission trouble codes stored. A flashing O/D light means the computer has stored a transmission fault. Reading the codes tells you where to look.
3. Throttle valve (TV) cable out of adjustment. One member said the TV cable at the throttle tells the transmission how hard you're pressing the gas, and a bad adjustment can cause hunting.
4. Burned fluid or internal wear. Dark, burnt-smelling fluid means the transmission has overheated. Clean fluid doesn't prove it's healthy, though.

What it usually costs

One owner said a speed sensor costs under $20. Owners didn't post other prices.

Is it safe to keep driving?

Random downshifts and hard shifts can surprise you in traffic. Drive gently and get it checked; don't tow with it until it's fixed.

DIY or shop?

Speed sensors and the TV cable are usually DIY. Code reading may need a shop, and internal repairs are shop work.

What owners report

• In 1996 Ford E250 - Tranny Problem on Car Talk, a 1996 E-250 with a junkyard E4OD worked for about 11,000 miles, then started revving high in first and slamming into second. A member said to check the fluid color and smell, drop the pan to look for debris and change the filter and fluid. The owner had been told to try a speed sensor, which costs under $20.
• In Strange problem with overdrive switch and cruise control...1995 Ford E250 van on Car Talk, a 1995 E-250 had a years-long problem where the cruise cut out, the O/D off light flashed and the transmission slammed into gear. Members said a flashing light means the transmission computer has stored a fault and to have the codes read. The owner's mechanic found a speed sensor that wasn't reading right and replaced it.
• In 96 Ford E250 Van constant gear hunting please help on Car Talk, a 1996 E-250 bought to make into a camper kept hunting between gears. Members said to tighten the loose spark plugs first, scan for codes, and check the adjustment of the throttle valve (TV) cable, which can cause hunting when it's off. One warned that clean fluid doesn't prove a transmission is healthy.

Quick tip

Start with the sensor and the cable before anyone talks rebuild. They're cheap and common causes on these vans.
