SOURCE: 99 Mercury Cougar has reverse but no forward gears

check the oil lever in the transmisson assuming it's automatic, if the fluid level is fine then with it in gear running and the brake on look to see if the drive shaft is turning, if it is then you have a prboblem with the drive shavft depending on engine size and wheather it's front or rear wheel drive. if it's not turning then you have a transmisson problem. If this is helpful please rate.

SOURCE: 91 Toyota Previa AWD - Swap original engine for Previa Supercharged engine

I do a lot of work on Toyota Previa before; including rebuilt engine, swapping engine and transmission and lot of things in between, but never swap a normal aspirated engine to a supercharged engine or diesel. Since i have some experience in Previa, I would like to share my opinion with you regarding your plan to swapping the normal aspirated Previa engine to a Supercharged engine. When you do a swapp like that, you will not only be dealing with just swapping engine, but some wiring, computer, throttle body, air cleaner assembly, extra frame and pulley on the accessory items, transmission as well as a right rear end to get the correct gear ratio to accomodate the new engine and transmission. I can go on even more, but let me tell you this, beside less headache, it would definitely cheaper if you were to find a Supercharged Previa and fix it up. However, if you are totally motivated to do this project, keep in mind, this engine swap will be a long term and time consuming project.l I wish you best of luck and have fun!

Where is the power steering temperature sensor on 1993 Toyota Camry v6


On some Camrys the radiator fan is run by hydraulic pressure from the power steering pump. I think the sensor you mention is the engine coolant temperature sensor, which is in the circuit which operates the fan when the engine becomes hot. If this fails the engine will overheat, yes. The fan does not cool the hydraulic fluid from the pump.

If your power steering fluid gets low the same thing can happen, but you would notice immediately as the steering would become intermittently harder.

We repair our Toyota Lucida automatic transmission because in runs on reverse only. Our problem now is that it will start to move forward only, once the engine RPM was between 1800 to 2000. Another thing,...


The problem concerning low gear locked up sounds like a bad primary shift solenoid (located on the valve body internally) the other issue with the forward gear only engaging with the rpm up to 1800 could be inadequate hydraulic pressure (a transmission front pump issue), most likely there is no problem with the pump if when shifting the selector lever into reverse it engages quickly and normally. This may be a transmission computer issue and I would recommend having the dealership do a diagnostic check on the transmission to eliminate the computer as a culprit. transmission problems are very difficult to figure out and before spending a lot of money get the electrical diagnostic done first.

How do you make previa awd into rwd.


The Previa has a special hydraulic center clutch. To convert it to rear wheel drive it would be necessary to replace the whole drive train. Disconnecting the front drive shaft on a 4 wheel drive vehicle will only save you a very small amount of of fuel. The only way to see a substantial fuel savings is by disconnecting the front drive axles from the wheels. This is what manual hubs do and that is why they are still popular.
To see even more fuel savings you would need to remove all of the front drive components and this would remove several hundred pounds and ever bit of weight that you can remove adds up to more fuel savings. But now you will end up changing the center of gravity and the balance of the vehicle.
I have made the assumption that you are trying to increase the fuel mileage of your Previa. Is this correct??
So in the long run you are looking at a major rebuild of your Previa. It would be less costly and less of a headache to go buy a smaller more fuel efficient vehicle.
I know that this isn't the answer you were looking for but this is the proper answer. I hope this helps.
Thanks,
rich

Toyota previa 1993 startup problems


Does it spin at all? If not either the starter is bad or the engine is seized. Try to turn engine with a socket wrench on the crank pulley bolt. Anything happen to the truck just before you had starting problems (drive through a deep puddle, overheat the engine, lose oil pressure, blown head gasket)? If it was deep water the engine could have hydraulic lock from water in the cylinder(s), remove the spark plugs and try to turn it over with the starter. If it turns over clean, dry and re-install the plugs. If it overheated, ran with low oil pressure, or the oil was contaminated with coolant the engine is probably seized.

Oil pump


If you are takling about the external oil tank, you don't need the pump, you need to replace the oil tank level sensor.
