46RE and 47RE units (and some 42/44RE units after 1996) use an interesting method to energize the coil of the transmission-control relay. As we all know, the switch part of the transmission-control relay is what provides battery power to the solenoids when its coil is energized.
I hate to discount anything. When you drop your prices you show weakness. It makes your customers think you are easy to take advantage of. The problem is that once you start to drop prices you tend to keep doing it. Before you know it your profit is all gone and your customers are in complete control of your business.
A 1995 BMW 325i equipped with a 4L30-E transmission came into a transmission shop. The customer was referred to the transmission shop by a technician at a general service facility because of a “check transmission” light and the torque-converter-slip code that he found during his inspection.
There are many parts that technicians take for granted and replace routinely without understanding the technology and engineering necessary to produce these parts. One of the most-common replacement items used by our industry is the drive chain. Once limited to transfer-case designs, drive chains were a natural way to transfer power between parallel shafts in front-wheel-drive automatic transmissions.
Some 1996-2003 Ford Explorers, 2003 Lincoln Aviators and 1997-2003 Mercury Mountaineers have “neutral tow” capability.
4R70W units in 2000 & later Ford and Lincoln/Mercury vehicles may have a rattle or clicking sound until the 1-2 shift is completed.
Ford Motor Co. introduced a new rear-drive transmission with the designation 4R70E or 4R75E at the start of production for 2004.
Technicians may have difficulty translating the readings for transmission-fluid temperature, since most scan-tool data for TFT is represented in DC voltage but most manuals show only resistance charts.
