Small bubbles in the fluid on the dipstick is a common occurrence. It is just one of the signs that the transmission fluid needs to be changed, along with color and smell. When the color is turning brown or the fluid smells burnt, have the fluid changed. None of these indicators necessarily means that the [...]
Simply put, it means that as the vehicle attempts to move from a stop, the engine revs and the vehicle barely moves or doesn’t move at all. OR, when the transmission shifts from one gear to the next, the engine revs during the shift rather than smoothly shifting to the next gear and the engine [...]
At first, this may sound like a reasonable request, but think about it. By taking your vehicle into a repair facility after getting a “worst case” estimate, you have essentially given your approval for the worst case cost regardless of the real repair cost. Do you really want to set yourself up like this? Second, [...]
Translated, the code means that the torque converter clutch is slipping. Beginning in 1980, GM modified their torque converters from a simple fluid coupling device between the engine and transmission by adding a piston to create a mechanical connection to increase gas mileage. When these transmissions evolved into computer controlled units, sensors monitor the slippage [...]
I suggest you take the van to a local ATRA transmission shop where the transmission can be evaluated “hands-on” to determine the present condition of the transmission. They should be able to point out any problems relative to the operation of the unit, and by removing the transmission pan, they can check for an accumulation [...]
This is probably the toughest question to answer because if you knew what you did incorrectly, you wouldn’t need to ask. These faulty results could be termed “unintended consequences.” You were simply trying to repair, modify, or perform maintenance on your transmission but the results were not satisfactory. I’m not trying to be curt, but [...]
Since the symptom relates to both forward and reverse, I suspect that the problem is thick fluid when its cold. When the vehicle sits overnight or a long time, fluid in the torque converter drains back into the pan area of the transmission. When the engine is started, the fluid is picked up from the [...]
The noise you describe is probably coming from the front drive line yoke splines at the transmission output shaft. It is very common that the wear in the splines causes “slop” that allows some “extra” rotation. When braking the vehicle, the drive shaft “holds” the transmission shaft back. When accelerating, the transmission output shaft “drives” [...]
This is a very common problem with some of the late model Ford overdrive transmissions. The source of the problem lies in the torque converter clutch that chatters as it engages causing a vibration to be felt. While this would seem to be a major warning sign of failing transmission, this will usually be cured [...]
Technical Bulletin #325 4T40-E Fluid Level Inspecting the fluid level on a 4T40-E is similar to inspecting the fluid level on a manual transmission. It uses a fill plug (oil level control plug) rather than a fill-tube and dip stick. To inspect the fluid level, follow the procedure below. Caution: Removal of the [...]
