Driving 65 MPH and engine rpm goes to 7K. Not in O.D. light comes

ever do a tune up? full 60k miles listed tuneup.
id bet 90% chance that fixes it.

no year.
no car stated.
you kidding right?
is it a carb car or EFI ?????
tell more get more..... for sure...

DATA:
7K (wiki)
The 1.8 L (1,781 cc) 7K was first introduced in 1983. Cylinder bore was 80.5 mm (3.17 in) and stroke was 87.5 mm (3.44 in). Output was 80 hp (60 kW) at 4600 RPM and 103 lb·ft (139 N·m) at 2800 Was available with a 5 speed manual & 4 speed automatic transmission. Available in both fuel injected and carburetted configurations, the 7K produces much more power and torque compared to the other K engines however it is a lot less 'rev happy' due to having such a large stroke.
7K is available in KR42 Townace SBV vans (1997-2007) using a large G52 5 speed gearbox (Same bellhousing to box pattern as W55), or automatic.
Applications:

• Toyota Kijang/Toyota Revo/Toyota TownAce

check for problem drive line "U" joints or cv joints

Check for a transmission speed sensor fault (OBDII scan). Loss of speed sensor signal will result in no torque converter lock up, and no overdrive. Also transmission filter should have been changed at 80,000 miles. Age of your vehicle(1994) warrants the filter service. Transfer case (4WD) needs to be serviced as well.

Replace transmission.

bad to worn out oil pump or excessive oil passage clearances that allowing more oil to pass thru them at a lower pressure due to the bigger opening. It can be a sign of an emminant engine failure due to oil starvation.

I had the same problem, replacing you thermostat should do the trick, i spent 8.99 on a new thermostat and 99 cents on a seal. For some reason engine temperature affects the transmission shifting. Good luck

Not sure what is causing it, but it sounds like you're running on 3 cyllinders. Check plugs, wires, timing . timing belt may have jumped, bad injector, low fuel pressure.

The rpm is too low. let an expert reset to 3.4 for u.

Possible transmission problem, take the car for a scan.

Automatic transmission are complex systems. The shifting of gears is based on a number of things like bands, speed, acceleration, deceleration, manifold back pressure, RPMs, temperature, etc.
Sometimes the electrical ground connection for the transmission can become corroded which causes poor shifting.
Since you are getting an error code, you should get a readout for it. Many auto supply store like Advance Auto will loan a meter for you to get a readout. Call up some stores to find one.
