Does the 4R70W have overdrive?
Does the 4R70W have overdrive?
The 4R70W carries a 0.70:1 OD gear. The numerically higher First gear of the 5R55S is great for most 10-second and slower applications, as it helps these heavyweight cars off the starting line.
Why is my Ford Expedition not moving forward?
I checked the transmission fluid and there was a fluid in it, however the engine oil level was very low, so I immediately added some engine oil and trans fluid but the truck still will not move forward or backward.
What causes a Ford Expedition to stall at a stop?
Bad Solenoid. When your Ford Expedition stalls at a stop, just as it would if it had a manual transmission and you neglected to push in the clutch, that’s a sign that one of the solenoids is malfunctioning or has gone out.
How does the transmission work in a Ford Expedition?
The Powertrain Control Module (PCM) and its input/output network control the following transmission operations: Torque converter clutch operation. The transmission control is separate from the engine control strategy in the powertrain control module, although some of the input signals are shared.
What are the solenoids for Ford AODE / 4R70W?
When you build, use new Torringtons if possible. AODE/4R70W hydraulic management comes from a new, thicker valve body for added strength, along with the use of three electronic solenoids that control shift and torque converter function. Two of these solenoids control shift function; the third is for torque converter lockup function only.
What’s the problem with my 4R70W automatic transmission?
4R70W automatic transmission problems boil down to two basic types of failure. One, the most common, is caused by some sort of electrical failure and which causes the vehicle’s computer to command the automatic transmission to stay in 2nd gear no matter what the vehicle’s speed.
Are there any problems with the AODE 4R70W?
There is nothing electrical about reverse gear in the AODE or 4R70W transmissions. You could have a bad Low/Reverse Band, or a bad Reverse clutch pack. To top i have a 2004 f150 with 4r70w tranny. installed a factory tech plate mod shift kit last weekend. all kinds of problems now.
Why is my 4L60-E transmission not upshifting?
In ‘Limp In Mode’, the automatic transmission will not downshift or upshift at all. The usual cause of this condition is a bad shift solenoid… although some internal mechanical problem/damage can also cause this.
