I just had this problem and had to replace the torque converter. Also the two three solenoid was bad..
Check trans fluid level. If the fluid is up but smells burned or is not a nice bright red color, you may have serious transmission problems.
when the river water suddenly falls from sufficient height it is said to have formed a waterfall .
Check wiring all along the harness. If the tranny is shifting up or down suddenly and for no reason there could be a short in the harness. 90's ford had a problem with this. May need a new harness or have to make one up yourself.
System could have a humidistat installed...
try your output speed sensor
What can cause the RPM on a car to jump while driving is a problem with the transmission. It could be a problem with the gears in the transmission itself.
There is no course specifically for it. If the driving school you went to had a Super 10 transmission, then you have a chance to learn it. If you know how to split gears with a 13 or 18 speed transmission, you've pretty much got the basics of shifting Super 10 down - you just have to get used to the shift pattern. When you're in gear, you push the knob on the side of the transmission forward, let off the gas for a good two seconds, then get back on the accelerator. If your RPMs suddenly spike way high when you put your foot back on it, you've missed the gear. Let off the gas again, and you can pretty much tell when it catches. When you move into the next shift motion, push the knob back to the rear and then proceed with the next shifting motion. It's really not difficult - just takes a little getting used to.
Change the transmission fluid and filter. If you see no improvement, take it to a transmission shop. We had a similar problem, and it ended up being a sensor in the transmission. I have a 1998 v6 which started to do the same thing. I was told by the transmission shop this is not an uncommon problem with Ford products. We replaced sensors, servo, solenoid, etc., problem kept coming back. Last time it was a valve body repair. It's still doing it. Next step is a new tranny - more likely I'm gonna trade it in for a new Honda. Good luck!
Check the transmission fluid level...no fluid...no go. Automatic transmissions are fluid or hydraulic driven, unlike standard or manual trannys where they use exclusively gears. If the fluid level is not sufficient, it will not move. If the level is just low, it will slip or slowly engage and will not shift properly.
There are several things that can cause your 1986 Nissan 300 automatic transmission to send you a start leaking fluid the most common cause is a blown seal in the front of the transmission. There is a seal in the rear of the transmission. The transmission pan gasket can be leaking.
Sounds like your transmission is low in fluid.
It will obviously be a major blow but the city will have sufficient notice of it happening, so sufficient time to find new work. The oil won't suddenly stop all at once. The North Sea fields are considered to be past their peak.
