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)
