Transmission engages but does not drive and makes a whineing noise when in park

Toyota 4 Runner has either auto transmission or manual transmission. If it is auto trans, it could be due to the following reasons:
1.Wrong grading and classification of transmission oil. (ATF Dexron II).
2. Clogged transmission filter. (Clean or replace)
3. Worn out clutch friction discs and pressure plates. (replace)
4. Broken fly wheel and/or torque converter. (replace)
5. Check transmission control knobs and switches for if they are at their actual position where they are supposed to be.

Gears in 1990 Toyota 4 runner grinding and not engaging

I'm assuming it's manual, check your clutch slave cyl level. You may be low on fluid. If you check the slave cyl and it has good travel and decent pressure your transmission will need to be removed to inspect clutch

Overdrive dosen't shift in.

Make sure u have a good thermostat in it. The engine temp must be at certain temp then a signal is sent to the transmission so it will shift into overdrive. Bought my 4 runner,91, was shifting fine until started getting cold then stopped all of a sudden. Checked the thermostat and it was in but had been gutted which allowed the engine not to warm up sufficient to allow the trans to shift into overdrive. Changed thermostat about $8, hasn't skipped a beat since.

I just purchased a used toyota 4 runner,1998, the transmission only engage reverse and not drive

I think you know you need a transmission, the only check that you can do is FLUID check f its to low the truck wont move, check for transmission codes, if oe of the codes is for line pressure solenoid that could be the entire problem, one more thing take a look at the radiator coolant if the color is like a pink shake the radiator is damage mixing coolant and transmission fluid.

I have a 1994 Nissan pickup. v6 manual trans. I get a loud hum as I drive. But when I press the clutch in, the hum stops. release clutch and hum starts. Could this be the Clutch fan?

No, By pushing in the clutch to stop the hum all you are stopping from turning is the transmission and ( transfur case if 4 wheel drive ) the engine is still running ..and some parts in the rear differential . I have had 4 nissan pickups and currently drive a 1995 pickup, without actually hearing the noise I would look toward the transmission, these Manual transmissions are very prone to bearing failure. This has happened to 2 of the one's I have had including the one I have now. You can also see as time goes by if the noise is quieter in fourth gear than others because this is direct drive and not as many trans bearings are involved Good Luck

1989 toyota 4 runner speedometer not working. does it have cable that runs to the gauge from the transmission or is it electrical? where should I start the troubleshooting

Yes it has a Cable! Does the odometer work? If so the problem is in the Speedometer head. If not you should soon be getting a check engine light on with a code that indicates a Vehicle speed sensor problem (VSS). The you should look to a broken cable.

1st, 2nd gear and reverse will not engage on my 4 speed manual transmission. what is the problem and how should i go about getting it fixed?

Sounds like the transmission is worn out. It could be rebuilt or call around to the junk yards and see if any has a good clean used trans.If you get a junk yard one change the fluid before you drive the truck.
