THIS BULLETIN CANCELS GMC TSB 88-T-144. THIS BULLETIN IS BEING UPDATED TO ADD AN ADDITIONAL MODEL YEAR AND CHANGE THE PART NUMBER OF THE CONVERTER, DATE 08/01/88.
Some 1988 and early built 1989 S/T trucks with a 2.8L engine may exhibit a higher than normal catalytic converter odor during operation. This odor condition can be reduced by installing catalytic converter, P/N 25104271. A new converter with nickel will enter production in the near future. VIN breakpoints were not available at the time of publication. Parts are expected to be available on January 1, 1989. Until then, normal parts orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort
to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in place.
