5 gear
What does it mean when it says wrong 5th gear ratio code
|
Welcome to the forum
I assume an automatic transmission What year and what engine size? In general it means one of the 3 speed sensors in the transmission is showing wrong shaft speed, it could be sensor problem or mechanical problem if shaft speed is actually faster or slower than it should be. If it was a sensor issue then there would most likely be another code with current code. Also post the EXACT CODE number you have, 99% of Code translations into english, or any other language, are often misleading Is the transmission shifting into all 5 gears? Are there any other symptoms, i.e. slipping, hard shifts, slow Reverse engagement? What does the trans fluid look like? what does it smell like? |

Just rebuilt it now it says wrong 5th gear ratio that's all my buddy scanners reads it's a 5R55E automatic transmission |

So a 4.0l engine, 2.3l and 3.0l used 5R44E
No Code Number? Transmission codes start with P07 then 2 more digits P0735 might be it If trans was rebuilt recently then I would recheck fluid level, could still have some air inside. There is no "Thats the problem" with P0735. Computer is just reporting that when it tells transmission to shift into OverDrive(5th) it is not doing so Ratio is the engine RPM compared to driveshaft RPM In 4th gear the ratio is 1 to 1 so if engine is at 1,000rpm, driveshaft will be at 1,000rpm, 1 to 1 ratio OD(5th) is .75 to 1 ratio, so if engine is at 750rpm driveshaft will be at 1,000rpm Transmission has speed sensors inside and final sensor(on 2001 and up) is the speedometer sensor, OSS-output shaft speed sensor So computer is expecting to read Engine RPMs as 75% of OSS(driveshaft) RPMs after it uses solenoids to shift transmission into 5th gear Now on the 5R44E or 55E 5th gear(OD) is also used as 2nd gear, yes, lol, as funny as that sounds 2nd gear is actually 1st gear with Overdrive turned on. So Ford changed the 4R 4-speed into the 5R just using computer software......"very clever these Americans" And it works well, so how does your 2nd gear work? |

No, thats not what was said
If your speedometer didn't work then maybe it could be OSS sensor And you would also get a different code for that P0500 Vehicle Speed Sensor Malfunction P0501 Vehicle Speed Sensor Range/Performance P0502 Vehicle Speed Sensor Low Input P0503 Vehicle Speed Sensor Intermittent/Erratic/High OR P0720 Output Speed Sensor Circuit Malfunction P0721 Output Speed Sensor Range/Performance P0722 Output Speed Sensor No Signal P0723 Output Speed Sensor Intermittent What I said was "There is no "Thats the problem" with P0735 code" Here are most, but not all, of the codes the computer can select from when it detects a problem in transmission: P0700 Transmission Control System Malfunction P0701 Transmission Control System Range/Performance P0702 Transmission Control System Electrical P0703 Torque Converter/Brake Switch B Circuit Malfunction P0704 Clutch Switch Input Circuit Malfunction P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input) P0706 Transmission Range Sensor Circuit Range/Performance P0707 Transmission Range Sensor Circuit Low Input P0708 Transmission Range Sensor Circuit High Input P0709 Transmission Range Sensor Circuit Intermittent P0710 Transmission Fluid Temperature Sensor Circuit Malfunction P0711 Transmission Fluid Temperature Sensor Circuit Range/Performance P0712 Transmission Fluid Temperature Sensor Circuit Low Input P0713 Transmission Fluid Temperature Sensor Circuit High Input P0714 Transmission Fluid Temperature Sensor Circuit Intermittent P0715 Input/Turbine Speed Sensor Circuit Malfunction P0716 Input/Turbine Speed Sensor Circuit Range/Performance P0717 Input/Turbine Speed Sensor Circuit No Signal P0718 Input/Turbine Speed Sensor Circuit Intermittent P0719 Torque Converter/Brake Switch B Circuit Low P0720 Output Speed Sensor Circuit Malfunction P0721 Output Speed Sensor Range/Performance P0722 Output Speed Sensor No Signal P0723 Output Speed Sensor Intermittent P0724 Torque Converter/Brake Switch B Circuit High P0725 Engine Speed input Circuit Malfunction P0726 Engine Speed Input Circuit Range/Performance P0727 Engine Speed Input Circuit No Signal P0728 Engine Speed Input Circuit Intermittent P0730 Incorrect Gear Ratio P0731 Gear I Incorrect ratio P0732 Gear 2 Incorrect ratio P0733 Gear 3 Incorrect ratio P0734 Gear 4 Incorrect ratio P0735 Gear 5 Incorrect ratio P0736 Reverse incorrect gear ratio P0740 Torque Converter Clutch Circuit Malfunction P0741 Torque Converter Clutch Circuit Performance or Stuck Off P0742 Torque Converter Clutch Circuit Stock On P0743 Torque Converter Clutch Circuit Electrical P0744 Torque Converter Clutch Circuit Intermittent P0745 Pressure Control Solenoid Malfunction P0746 Pressure Control Solenoid Performance or Stuck Off P0747 Pressure Control Solenoid Stuck On P0748 Pressure Control Solenoid Electrical P0749 Pressure Control Solenoid Intermittent P0750 Shift Solenoid A Malfunction P0751 Shift Solenoid A Performance or Stuck Off P0752 Shift Solenoid A Stuck On P0753 Shift Solenoid A Electrical P0754 Shift Solenoid A Intermittent P0755 Shift Solenoid B Malfunction P0756 Shift Solenoid B Performance or Stock Off P0757 Shift Solenoid B Stuck On P0758 Shift Solenoid B Electrical P0759 Shift Solenoid B Intermittent P0760 Shift Solenoid C Malfunction P0761 Shift Solenoid C Performance or Stuck Off P0762 Shift Solenoid C Stuck On P0763 Shift Solenoid C Electrical P0764 Shift Solenoid C Intermittent P0765 Shift Solenoid D Malfunction P0766 Shift Solenoid D Performance or Stuck Off P0767 Shift Solenoid D Stuck On P0768 Shift Solenoid D Electrical P0769 Shift Solenoid D Intermittent P0770 Shift Solenoid E Malfunction P0771 Shift Solenoid E Performance or Stuck Off P0772 Shift Solenoid E Stuck On P0773 Shift Solenoid E Electrical P0774 Shift Solenoid E Intermittent P0780 Shift Malfunction P0781 1-2 Shift Malfunction P0782 2-3 Shift Malfunction P0783 3-4 Shift Malfunction P0784 4-5 Shift Malfunction P0785 Shift/Timing Solenoid Malfunction P0786 Shift/Timing Solenoid Range/Performance P0787 Shift/Timing Solenoid Low P0788 Shift/Timing Solenoid High P0789 Shift/Timing Solenoid Intermittent As you can see the computer can be pretty specific, especially if it is a wiring or electrical device issue, when it decides to set a code. ONLY getting P0735-Gear 5 Incorrect ratio, to me, would mean a mechanical issue, blocked passage, low pressure, ect........not a wiring or electric part issue, so not a sensor or solenoid issue Never used Snap-on code reader, it should have a setting(or sub-menu) to get exact code numbers, not just definitions, wouldn't be much good as a reader if it didn't, definitions are not all that accurate |

If there are no other codes then the rebuild missed something or didn't get the valve body on correctly.
You never answer the question about shifting? Does it shift normally and does it shift into overdrive(5th)? |
