Many of us remember the “gasoline shortages” of 1973 and 1979. Some sections of the U.S. were hit harder than others. The New York metropolitan area, for example, still had the problem months after the rest of the country had all but forgotten about it. It was as if we were supposed to suffer longer so the message would be heard loud and clear throughout the country that gas wasn’t going to be a cheap commodity anymore.
Finding the cause of an electrical problem on a Ford Expedition requires some detective work
A 2002 Ford Expedition equipped with a 4.6-liter V-8 and 4R70W transmission came into the shop with a host of solenoid electrical codes.
Have you ever wondered where those extra O-rings go that are left over in the kit bag after you’ve completed an overhaul on a transmission? Most rebuilders, including myself, will twist-tie them to a bellhousing bolt hole and say, “Must be some spare pieces for the R&R guy!”
The 4T65-E was introduced in 1997 in several vehicles equipped with the supercharged 3.8-liter engine, and some non-supercharged 3.4- and 3.8-liter engines. It was considered to be the big brother to the 4T60-E transaxle.
Beginning at the start of production for the 1999 model year, the planetary pinions on both carriers in THM 4L80-E transmissions were produced 10%thicker than those in previous models.
In a 1999 Chevy truck with a 6.5-liter diesel engine and 4L80-E transmission, the optical/fuel-temperature sensor was responsible for a complaint of 2-3/3-2 and 3-4/4-3 shift shuttles at cruising speed with 25%or greater throttle opening.
