When I turn on the 1999 LX 470 / Toyota Land Cruiser 100 engine with Transmission Gear in P, and 4WD Gear in H, the truck can only move forward in all gears except P and R. When in N, it even moves forward. In R, the truck won't move. I have the truck Jack up and I can see the tire spin so I know those tire spin. If I put the truck down, I have to press the Gas Padel like 2000rpm or more to move the truck forward just a little bit. The Reverse won't work.
If I put the Transmission Gear in N and 4WD Gear in N as well, it works. But then if I try to move the 4WD Gear back to H, it would produce a loud Grinding noise (The engine is still On), so I didn't do it afraid of breaking anything. If I try to move the 4WD Gear to L, it did the same thing.
At this point, if I move the Transmission Gear from N to any Gear, it's all OK, but if I move to P, it also has Grinding noise, but it sounds a lot different than the 4WD Gear grinding noise describe above. I guess it is Transmission Grinding instead of Transfer case Grinding noise.
I have to turn the engine off in order to move the 4WD Gear from N back to H again. But then it will just return to the same situation as described above i.e. the truck won't move. If I jack the truck up, I can see the front tire spin (some spin at the rear tires too); If I switch to R, there is no reverse. The CDL works ok. But turn it on or off won't make any difference.
What happened before this all happened: I was trying to solve the chucking problem.
1. I flush the transmission oil
2. I grease the Drive Shafts
3. Then I still hear chuck noise when drive so I change the U-Join on the rear and front Drive Shaft.
4. I install the rear Drive Shaft back first; then w/o front Drive Shaft, I take the truck to a spin. But as long as I leave the driveway which a little uphill driveway, I feel a big chuck, and the reverse no longer work. I have to drive forward in CDL / Low mode and the Truck only drives forward.
What had I done trying to solve the problem so far?
1. I read many posts here and the shift/lock control switch (The shift linkage) is still operating, because the truck will start in P & N only.
2. I change the transmission fluid again (last changed is a month ago) but it won't help.
3. Now the ABS and Break malfunction light just on but I think it is coincident and should not related to this issue.
Thank you so much for any advice would be very appreciated!
