2011-Up Ford Mustang’s Getrag MT82 6-Speed Manual Transmission
Most of the manual-transmission business in the light-duty market is concentrated in the sports or muscle-car vehicles. Ford Motor Co. has had a highly successful run with the Mustang.
For many years Tremec, a world-class transmission manufacturer based in Mexico, supplied the transmission products for the Mustang. We have seen the T5, T45 and TR3650 five-speeds and the TR6060 six-speed. These are all quality transmissions that are still finding their way into our shops today.
Quit Dimpling Those Converters
This all started with my looking at multiple converter failures caused by the converter bolts damaging the backs on Toyota A245E/A246E transmissions used with the 1.8-liter engine. We also see this in other Toyota applications, maybe more so than with other vehicle manufacturers.
My intentions were to order some factory bolts to get the proper dimensions and possibly send these reman units out with new bolts, either OE or an economical replacement bolt. I was hoping this would eliminate any confusion for the R&R technician as to which bolts were the proper ones to go into the converter, hence eliminating unwanted warranty repairs.
4R/5R55E: Engine Stall on Engagement after Rebuild
A local general-repair garage brought a 5R55E transmission and converter to a transmission shop for a rebuild. The transmission came out of a 1997 4.0-liter Ford Explorer with 216,456 miles on the odometer. The shop had the correct rebuilt transmission and converter in stock, so exchanging the change-over parts was all that was necessary to return the unit to the garage.
Listen to the Customer
The customer brought his 2005 Ford Taurus to our shop with a complaint of an intermittent jerk at highway speeds. The customer had gone through the trouble of documenting the times that this jerk appeared, the temperature at which it occurred and under what driving conditions he was feeling the intermittent condition. He also told me that another shop had recently rebuilt the transmission. I took the time to listen to him and to ask several follow-up questions that would help me correctly identify the problem. It occurred only once every couple of days.
Don’t Forget the Basics
Instead of choosing just one success story that applies to one vehicle, how about writing something that applies to all vehicles? The thought that I want to convey is to pay attention to the simple things and small details alike, both when diagnosing a problem and when removing and reinstalling a transmission.
It’s not just the Transmission
Recently a customer called to get a quote for a 1998 Ford F-150 4X4 with the 4.6-liter V-8 engine and 4R70W transmission. The price was given and we had one in stock. A couple of days later they called and told us they needed the transmission. It was still in stock, but it was late in the day so we made arrangements to deliver it to them the next day.
The Fine Points of the BorgWarner 4411 Transfer Case
One of the best-selling vehicles produced by Ford Motor Co. is the Ford Explorer/Mercury Mountaineer SUV. These vehicles started production using the BorgWarner 4405 transfer case and had a huge production run.
Shift By Wire
This article presents a situation that ATSG technical adviser Gerald Campbell handled regarding a ZF 6HP26 in a BMW with Reno Partipilo, Sal Scardina and Joe Russo from Continental Transmission in Bridgeview, Ill. But before we can cover it, we first need to present a bit of information that will help to make sense of the problem and what it was that corrected it.
All Fired Up
The doodad we’re going to discuss here is an optional one that is installed by Ford Fleet Services, a subsidiary of Ford Motor Co. Ford Fleet installs systems in fleet vehicles such as police cars that include items like the flashing roof lights, sirens, Kevlar‚ lined trunks etc. Ford Fleet also installs a fire-suppression system, which is the one we’re going to discuss here.
Ford 4F27E Shift Strategy – a Different Way of Doing Things
The 4F27E transmission uses two on/off solenoids and three PWM solenoids to produce each of the shifts and converter-clutch apply, as the chart in Figure 1 shows. The EPC solenoid is used to control line pressure relative to engine torque. So far this sounds easy, but from a strategy standpoint, it progressively moves toward a “different way of doing things” when compared with what we are accustomed to.
Fun with Fords
As almost all of us are aware, a technician can easily create a scary nightmare when trying to mix and match parts while making repairs to some of Ford’s automatic transmissions. A classic example of this is interchangeability of the lockup solenoid (LUS) for the 1991 AXOD-E (AX4S) transaxle.
Something Is Missing!
Remember, earlier in the article I mentioned that this was a fleet vehicle. You know what happens with fleet vehicles; they borrow good working components from one vehicle and put it in the vehicle that’s not working. Now, maybe the fleet mechanic had every intention of replacing the borrowed part, but it never happened. It was forgotten, and the fleet mechanic on a different shift ran into the transmission stuck in 4th gear and sent it to this transmission shop.
