|13/18 Speed Enhanced Bearing Lube Upgrade Kit
To ensure proper front bearing lubrication during severe operating conditions of 13/18 speed models, Eaton released into production the forced lube system in November, 2000 for 1650 lb. ft. and above models. Note: All 2250 lb. ft. models are equipped with forced lube technology. For units built prior to the November 2000 date, there was no cost effective means to upgrade.
|14" Heat Exchangers
Failures of the 14ý heat exchanger which include internal leaks causing transmission oil and engine coolant to mix and broken mounting brackets causing external oil leak. High transmission sump temperatures and/or coolant GPM (gallons per minute) levels less than that required by Eaton will put the heat exchanger at a higher risk of internal failures.
|Addition of Fault Code 91 and revised Electrical Pretest

|Clutch Lubrication Requirements for UltraShift® PLUS Transmission
Unlike the Eaton UltraShift® automated transmission, Eaton UltraShift® PLUS transmission does require greasing during vehicle servicing. The UltraShift PLUS transmission has grease zerk locations for lubricating the clutch release bearing and cross-shaft bushing of the ECA motor in addition to the clutch release bearing and the bushing for the shaft of the ECA motor. Over lubricating these components may contribute to a slipping clutch by getting too much grease into the clutch environment.

Eaton Fuller has released 4 new convertible transmission models: RTOC-16909A, RTOFC-16909A, RTLOC-16909A-T2, RTLOFC-16909A-T2. These models were developed at the request of our customers, who wanted fleet type transmissions (9 or 10-speed transmissions without a splitter button) that could later be converted and sold as 13-speed performance models. The convertible series models have the same fit-up as RTLO-16913A and RTLO-16913-T2 models with the exception of the shift knob and air lines, which are similar to a 9-speed. Oil cooler and lubrication requirements will be the same as RTLO-16913A.

|Installing Clutch Inspection Hand-Hole Cover
Over the years it has been the practice in the trucking service industry when servicing Eaton clutch products the hand-hole inspection cover is not being reinstalled. Not reinstalling the clutch inspection cover after servicing of the clutch will leave a large opening which will allow contamination to be ingested into the clutch housing and the clutch itself.
|Interference between the Clutch Damper and Flywheel Bolts on Caterpillar Engines

Updated procedure for installing internal pump plug to prevent damage to O-ring. Damaged O-rings may cause mis-diagnosis of clutch housing gasket leak.
|Lightning 18-way ECU Connector
It is possible that the 18-way connector on the Lightning transmission ECU may exhibit ýFretting Corrosioný build up between the female connector terminals and the ECU pins. The tin coating of the female terminals and ECU pins may oxidize through heat cycles and vibration possibly causing ýFretting Corrosioný build up. The fretting corrosion build up may cause resistance levels to increase between the terminals and ECU pins. This may result with the ECU possibly logging an active/inactive fault code or to have an intermittent symptom.

| Low Lube Transmission Failures Caused by Radiator Repair or Replacement
There have been several instances of transmission failures caused by lack of lubricant. Root cause has been linked to a prior repair of the vehicles engine radiator.
|Lube Line Fitting Wear Causes Premature Clutch Failure
Wear of the clutch release bearing lube-line fitting at the clutch housing. In some cases the fitting wears through allowing the grease to escape, preventing it from reaching the clutch release bearing. This results in failure of the clutch release bearing. See photos for failure description.

|MD 200 - "Redtail Version C Required" Error
When turning the tool on an error message will be displayed on the screen. The error message is: ýRedtail version c required waiting for downloadý. The root cause of the failure is attributed to placing the batteries in the scan tool in reverse order. A change to the hardware prevents placing the batteries in backwards to cause this error in newer scan tools.
|MD 200 Link Tester Cable
Anyone who purchased a MD 200 series Scan Tool Kit that included the link tester function between April 2003 and March 2004 did not receive a Link Tester Cable (part number LT-CBL-01).

Mechanical transmission hard shift complaints may be diagnosed as a transmission problem but may actually be an OEM related issue. Potential causes may be OEM shift boots, levers, or controls. This has been known to drive un-necessary transmission repairs and costs to the customer.
|Minimal Lever Engagement on LL Models
Some customers with 8LL or 9LL transmissions may experience a complaint of minimal lever engagement or lever jump out in the rearward lever positions. This condition is caused by an improper machining operation at the shift bar housing resulting in casting interference with the shift blocks.
|Multi-Speed PTO Prelube Precautions
Several surface areas in the auxiliary section of the transmission must be pre-lubed when the transmission is equipped with the Multi-Speed PTO option.
