D3 always when driving around town after say 55 cruising you should then release the gas slightly and shift to D4 (OD) but don't forget to shift on the highway the extra rpm of running in D3 at higher speeds will burn more gas cause faster engine wear, and also could cause engine to over heat. just a simple answer to your problem.
Ford specifies Mercon Automatic Transmission fluid in the manual trans.
If it is an automatic transmission it should use Dextron 2 type of transmission fluid. If it is a standard it will use a heavy gear oil. Auto parts stores should have the volume needed if you are doing a fluid change.
A 1992 Nissan NX 5speed will use approximately 3 to 4 quarts of gear oil in the transmission. The gear oil can be purchased at any auto parts store.
You should use it every 40,000 miles to keep your transmission well lubricated.
Some auto parts place told me that the transmission, transfer case, and differentials use 75w90
NO... you should use a lower gear if you want to slow down not higher.
They are different, auto trans use hydraulic oil or ATF ( automatic transmission fluid ) and manuals use that or a very thick version of gear lube like 80w-90.
That manual transmission doesn't use gear oil. You can use Mercon ATF.
The trans does not use gear oil. The auto uses ATF+4 and the manual uses a special manual transmission lube.
Whether it is a manual transmission or an automatic transmission you should use Dexron 3 available at most auto supply stores.
There is no drive in a standard transmission car. In most cases you will have reverse, neutral, 1st gear, 2nd gear, 3rd gear, 4th gear, and 5th gear.
Use 10W40 non synthetic or 75w90 Gl3
