SUBJECT
Automatic Transaxle Diagnosis For Sephia/Spectra/Rio
This bulletin provides information related to diagnosing and correcting automatic transaxle concerns on all Rio and 1998 through 2001 MY
Sephia/Spectra vehicles built before 10/1/00.
Incorrect diagnosis of automatic transaxles and their control systems may lead to repeat repairs and/or cause unnecessary replacement of transaxle
assemblies.
Follow the procedures outlined in this bulletin for any of the following:
^
MIL on (and HOLD light blinking) and DTCs stored in TCM or ECM
^
A/T related drivability concerns, incorrect shift behavior or slip
^
No Forward or Reverse gear
To correct these concerns, perform the rework described below as required.
PRELIMINARY:
Familiarize yourself with the procedures outlined in TSB, Transmission/Driveline 003 (Revised), dated March 2002. Obtain an A/T Diagnosis
Worksheet.
Check for any stored (or pending) DTCs, record description and Freeze Frame Data. If circuit related DTCs (i.e., P0753, P0758, P0763) are stored,
repair those before attempting to correct DTCs that indicate malfunctions (i.e., P0732, P0733, P0740).
Check the vehicle's repair history to determine if this is a repeat repair. If so, note what previous repairs were done and whether they were effective. Use
repair history to aid in diagnosis and repair approach.
Inspection
Check A/T fluid level and appearance. If fluid is burnt or contaminated, transaxle may have to be replaced per instructions in TSB,
Transmission/Driveline 003 (Revised), before proceeding.
* NOTICE
Regardless of transaxle replacement, do not release vehicle until the checks and upgrades described below have been completed.
1.
Check software version of TCM (if the vehicle was built before 10/18/00), refer to TSB Transmission/Driveline 007.
2.
If TCM is correct, proceed to step 4.
Note:
The revised TCM will give current transmission data on 98 - 00 MY Sephias if you enter 01 MY on the Hi-Scan Pro scan tool.
3.
If TCM configuration is incorrect, replace per TSB, Transmission/Driveline 007.
