1995 nissan sentra automatic trasmission will not go into passing gear


Gear shifts happen depending on how far the gas pedal is
pressed & the load on the vehicle

Transmission pressures change as you drive under different conditions,so the shifts happen at different speeds

There is no passing gear

If you have a 4 speed,you have 3 forward gears & an overdrive
forward gear, plus torque converter lock-up

You saying you have no 4th to 3rd downshift or whatever

Maybe the transaxle is failing mechanically inside-worn out

O/D Off light goes off and on


the overdrive is the 4th gear. considering that it may not be an issue with your computer switching gears to fourth but an issue with the transmission itself. this light could be a signal instead of and engine warning light where the engine is fine but the transmission isnt.

2005 Corolla's manual trasmission shifts gears, it clunks


hi mate , sounds like the SPIGOT bearing its a little bearing that allows the gearbox to be at a different seed than the engine flywheel and if this is in bad condition it will take the gearbox front shaft to a higher speed than comfortable for gearshift , in the meantime when you go for 1st or reverse gear just engage a gear like 4th without taking your foot off the clutch and then go for 1st or reverse, this will stop the gearbox spining long enough for a smooth shif, oNLY USE THIS METHOD WHILE STaTIONARY and see a professional when you get time.

1996 Dodge Ram Transmission shifting problem


I had the same problem with my 96 Ram 1500. I thought I was going to have to pull it out and get it rebuilt or just replace it. That was at 134,000Km it's now got 210,000 and shifting like a dream. What I did to solve the problem was this, as follows:
1. No lucas transmission Fix makes things worse.
2. Get your self a new transmission filter and gasket
3. Grab Gunk transmission medic 12oz
4. Grab 7 Liters of Valvoline ATF+4 transmission fluid (Made for chrysler transmissions)
5. Drop the trans pan and drain all the oil, clean pan and magnet
6. start truck for 5 seconds and the pump will pour out another 1 liter
7. re-install filter, gasket and pan, then add your Valvoline ATF+4
8. Add, the valvoline, transmission medic and make sure you have the right level of fluid

That solved my transmission problems, instantly it was shifting better, I no longer had to let off the gas to make it shift. Now if you have large pieces of metal on the magnet, and it's totally covered in filings, you might want to consider rebuilding the trans. My magnet had usual clutch.         

Anyhow good luck, let me know if it did the trick for you.
