Scoping Out A Jeep Issue

This article is a “case study,” but the procedure used to find the root cause of this issue can be used on almost any application. We’ll use the scope module part of the Snap-On Zeus scan tool; is this the best scope out there? No, but the ease of use and the addition of the

47/48RE SFI-Certified Flexplate Shield

Loganbuilt has developed and manufactured the first SFI-certified 30.1 flexplate shield for diesel racing transmissions. SFI flexplate shields are a safety feature required by the NHRA for any vehicle running quicker than 6.40 ET in the eighth-mile, or 10.00 ET in the quarter-mile.  Flexplate shield requirements have been in place for years but they have

Chrysler/Dodge/Jeep 4XRE Transmissions No Movement

Complaint: A vehicle equipped with a 4XRE Series Transmission stopped moving suddenly soon after overhaul. Since an unmodified 4XRE valve body does not charge the torque converter in Park, the fluid level was check in the Neutral position, it was over full. The technician then removed the return cooler line to check for cooler flow

Hydraulics: Converter Limit Valves

This article is one of a series by Sonnax exploring how valves and hydraulic circuits work and what results when they quit functioning correctly.

Multiple Causes for P0562

A customer brought in a 2010 Dodge Journey AWD with the high-output 3.5-liter V6 engine and the 62TE automatic transmission. With a little more than 83,000 miles on the odometer, the complaint was for no upshifts and stuck in 3rd-gear failsafe mode. This concern had started out as an intermittent issue but now had become more regular.

‘Rebuilt’ salvage-yard transmission, hmmm …

We had a local general repair shop bring us a 2014 Jeep Grand Cherokee 3.6L V-6 engine equipped with a ZF 8-speed (845RE) transmission; they had just installed a “rebuilt” transmission that was sourced from a salvage yard. The customer’s stated concern was, “The place that built the transmission just said it needed to be programmed.” Needless to say, we knew that this was going to be an adventure.

Overdrive Solenoid Déjà vu All Over Again

About a month ago a customer came into our shop with a 2008 Chrysler Town & Country equipped with a 4.0 liter V6 engine and a 62TE transmission. He was complaining that it had a whining noise, and sometimes it would not shift and seemed to stay in the same gear. When the vehicle was hooked to the scan tool it had a code for the overdrive solenoid control circuit (P0760). The fluid was at the correct level and smelled like normal fluid; however, it was dark purple indicating possible metal contamination.

Finally, the truck shows its cards

We’ve all had to contend with intermittent electrical problems. These are typically the most difficult issue to pinpoint, as the root cause literally plays hide and seek with you. The following issue that I encountered belonged to a 2008 Dodge Ram 5500 in which the customer stated the transmission wasn’t shifting, and the check-engine light was on.

Problem-Free Pickup, Now This: Why?

This month I’m addressing the common complaint of intermittent and erratic torque-converter clutch cycling between 45-60 mph experienced in Dodge Cummins Diesel pick-ups from years 1998-2003. After 60 mph, the issue seems to go away. This has been a well-documented problem over the years with many bulletins published from the manufacturer.

Outta Sight!

We’ve all had to chase intermittent vehicle issues. What makes them so challenging is that you can’t fix what you can’t see. Sure enough, it always seems that the concern disappears when you’re trying to diagnose the issue in your bay.

This story is a similar case. We were diagnosing a 2002 Dodge Grand Caravan with a 604 transmission and 3.8L engine. Six months prior, the vehicle owner contacted us and said that the transmission would not shift and was starting off in 2nd gear. By the symptom description, the unit was likely going into failsafe mode. We scheduled an appointment, but the customer was a no-show.
