5 speed 1990 toyota 4wd,my transmission wont engage to first gear or reverse when engine is running but will in engage when engine is turn off

It sounds like a delayed shift issue, does the engine idle speed sound or feel like it is to high? That can cause this issue.

10 Most Common Transmission Problems

Did you check the transmission fluid level? if it is OK, then you need to have a transmission specialist look into this.

Hi do check gear linkages or cable adjustments.otherwise possible gearbox malfunction.

what speed are you driving at, in 4wd ? before it does this ?

Not sure if the 4runner requires you to stop before engaging 4wd or not. Need some more information on your vehicle, auto/manual, speed when you engaged 4wd.

MANUAL TRANSMISSION OIL GOT TOO LOW.CHECK MANUAL TRANSMISSION FLUID SOUND DRY.

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.

I see this is kind of a stale post, but i'll try anyway. First, check your clutch fluid reservoir. If it's full, you may have air in the line, a bad master cylinder, or slave cylinder, or your clutch is worn out.

You may need new motor mounts...if they are worn out this would allow additonal vibration from the engine to transfer to the vehicle body & doors . If it is 4WD then also check underneath for the center driveshaft mount. Higher mileage cars tend to have the mounts lose there ability to dampen engine movement upon engagement.

Any shop should be able to push on the brake and engage the transmission in drive or reverse and watch the whole vibration event happen.

Then it becomes a determination of which mounts to replace.
