Hi,
I did a T5 trans swap and referred to the online calculators as well as the tables and info at various websites to determine which driven gear I needed for the driving gear that I have with my tire/rear end gearing. The speedo still reads low. Improved, but still too low.
Speedo drive cable was cleaned, inspected, lubricated, and re-checked again later- no issues with the cable.
I then went with the very smallest driven gear available for use with my driving gear, and the speedo still reads low throughout the range, with it reading about 6 mph low on the highway now. It should be reading way high, at this point.
Any suggestions as far as what might be going on inside the speedo itself? Can the magnets lose power over time and require re-magnetizing? Speedo behaves perfectly otherwise - no bouncing or erratic movement...very smooth and quiet.
Any suggestions appreciated...
