If yes, print a copy of it and attach it to your packet. If not look up a TSB for this transmission and attach it. Then, in your own words summarize the TSB and add any additional info you believe to be pertinent.MeasurementsClutch, Band, or One-way Clutch# Frictions# SteelsConditionClearance SpecificationMeasurement BeforeMeasurement AfterAdjustment MethodTransmission EndplayOrganization (sign offs)Condition of fluid and/or material on bottom of pan:Diagnosis madeTSB foundValvebody removedPump removedTransmission disassembledTransmission case clean(Attach printout of check ball locations)# Check balls in case _# Check balls in VB_# Screens in case_# Screens in VB_Transmission assembledTransmission assembledTransmission assembledPump disassembledPump inspection before reassemblyTorque SpecsValvebody_Valvebody to case_Pump body to cover_Pump to case_Oil Pan_Transmission inspection before pump installationValvebody cleanValve freedom checkValve disassembled and reassembledType of fluid required_Capacity of transmission_Final check before pan installationTorque converter InstalledTransmission installed and filledFluid level & hoist run Test driveFinal checkTest DriveShiftSpeed (MPH)1-22-33-4Does the transmission engage into reverse with no more than a 1 second delay?

YESNOEvaluationDiagnosis0 PointsNo diagnosis was recorded before transmission was disassembled3 PointsDiagnosis was a guess, not based on specific reasons6 pointsDiagnosis was made based on sound reasoning, but some relationships were overlooked10 pointsDiagnosis was made based on sound reasoning and understanding of the clutch app chart, hydraulic, and electrical controls of the transmissionOrganization0 PointsSignoffs were not obtained at appropriate times, Specifications were not referenced, workspace poorly organized3 pointsSome signoffs were not obtained at appropriate times, some specifications were not referenced, workspace somewhat poorly organized6 pointsA few signoffs were not obtained at appropriate times, all specifications were referenced, workspace relatively well organized10 pointsSignoffs were all obtained at appropriate times, all specifications were referenced, workspace is clean, and organized. Individual components are disassembled and reassembled 1 at a timeCraftsmanship0 PointsTransmission was assembled with disregard for in-vehicle function and performance 3 PointsLittle attention was paid to proper assembly, disregard for the longevity of the rebuild6 PointsTransmission was correctly assembled, however, the rebuild was not complete (i.e. did not replace all bushings)10 pointsTransmission was correctly assembled with attention to detail (both in inspection and assembly) and completeness of the rebuildMeasurement0 PointsMeasurements were neither taken or recorded3 PointsMeasurements were taken, but not recorded at the time they were taken6 PointsA few (1-3) minor measurements were not taken or not recorded at the time of measurement10 PointsAll measurements were taken and recorded properlyTest Drive0 PointsTransmission did not operate correctly, results were not recorded, no real attempt at re-diagnosis was made(or no test drive)3 PointsTransmission did not operate correctly, results were recorded and re-diagnosis made6 PointsTransmission operates correctly, but results were not recorded 10 PointsTransmission operates correctly and results are recorded during the test driveTSB0 PointsNo TSB or inapplicable TSB2 PointsTSB attached, but no summarization5 PointsTSB attached and completely and accurately summarized6 PointsTSB ,which applies to the customer complaint about the transmission you are rebuilding, attached and completely and accurately summarizedRepair Order0 PointsNo repair order2 PointsIncomplete repair order5 PointsComplete and accurate repair orderParticipation0 PointsDoes not contribute to the success of the rebuild.
