ISSUE
Should repairs become necessary on a 4R70W transmission involving replacement of the forward or reverse clutch sungear, and/or the number five (# 5) thrust bearing, these service pants all must be replaced in combination. A mismatch of service parts may cause an internal noise or a loss of forward and/or reverse. A new service kit has been produced to eliminate the mismatch of service pants. This new kit services all 4R70W transmissions built prior to the 2004 model.

ACTION
A new Service Kit 4L3Z-7D234-M has been produced to eliminate the mismatch of service parts.

The kit contains the following:





^ A new two (2) piece number five (# 5) thrust bearing assembly (70234 bearing and 70235 race) (Figure 1)





^ A forward clutch sun gear (7A399) (Figure 2)





^ A reverse sun gear (7A019) (Figure 3)

SERVICE TIP

To install, refer to the latest version Workshop Manual for disassembly and reassembly of the transmission.

CAUTION
ALL COMPONENTS IN THE KIT MUST BE INSTALLED OR THE REPAIR MAY NOT BE EFFECTIVE AND MAY CAUSE AN INTERNAL NOISE OR LOSS OF FORWARD AND~OR REVERSE.
