Transmission moving/Park question too (1 Viewer)

[4WD Toyota Owner Magazine]

1. How much movement of the shift lever is considered normal during wheeling, or even hitting bumps in the tarmac? I'll be driving down a road here in town and hit bumps and if my hand is resting on the shift lever, i can feel it moving back and forth. Engine and tranny mounts...maybe wearing out?

2. With the front driveshaft removed from the truck, the 80 will slowly roll if on an incline, even with the tranny in Park. That kind of surprised me. Gotta ratchet up the E-brake to keep it from moving (unless on flat ground, of course). Is this normal?

Thanks!

The T-shaped main transmission shift lever, not the transfer case lever. It moves back and forth when the truck's suspension takes hit and dips in the road.

What year LC do you have? What year did Toyota go to the ECT?

4WD- not sure if it is normal, but mine does it, too. The tranny shift lever moves around quite a bit when going over bumps- it is esp. noticeable offroad, though.

tech_dog- I thought both the 442 and 343 trannies were electronically controlled? In fact, you should have a switch on your '94 labeled "ECT" for power mode, IIRC. In any case, the switch happened in '95.

Mine's a 1995 FZJ80.

Any thoughts on the rolling in Park thing with front driveshaft removed?

With the transmission in park the transfer case input shaft is essentially locked. Still, the center diff allows the two output shafts to rotate in opposite directions, which is possible with wheels off the ground or drive shaft is removed.

Lock the center diff to prevent this behavior.

Rich has got it. With no shaft to the front diff, the front diff output shaft can be rotated in the opposite direction of whatever the rear shaft is spinning when the vehicle rolls. With the shaft in place this cannot happen as obviously that action would simply be stopped by the front wheels and the truck is held firmly in position in Park like any other vehicle. Best to use the parking brake and have the center diff locked.

This is true whether you have the massive, capable and manly 442 or the wimpy and anemic 343.

As for movement, I'm thinking you are mis-remembering which lever is moving perhaps? The transfer lever moves a LOT. The tranny lever does not. If your tranny lever is moving a lot you should indeed take a glance at your drivetrain mounts.

Thanks Rich and Doug.

I think I'd better check the mounts--I have never even felt the transfer case lever while in motion, only the tall, R/N/D/2/1 lever. It moves around quite a bit when the truck is going over rough terrain. Hmmm. Tranny mounts shot, maybe?

Are you talking about the transmission shift lever, or the xfer case? The transmission lever is just an electronic switch with no mechanical connections.

This is most definitely incorrect. I've never taken apart a 95 plus but on the 91-94s the T handle transmission shifter is most definitely bolted right to the top of the transmission with shift linkages. I imagine the 95 plus are similar. Any driveline vibrations can be felt through the shifter if they are significant enough. It is dampened by the rubber mount where the transmission connects to the crossmember. I've always been able to feel more of a vibration on the transfer case shifter because it is dampened less and is directly connected to the drivelines.

diff lock

Is your center diff locked? You should not be driving around w/o a front shaft unless you have your center diff locked.

 

[tech_dog]

Yep... looks like I'm wrong.

For reference, here's a link to an image of the shifter:

I must have just flipped over the cover, saw the bottom of part #57, and not noticed part #925 going out the bottom.

My bad.

My 97 tranny and TC levers off road and while hitting bumps... so did my mom's 00 4Runner when it was new and my 02 Tacoma when it was new... I'm pretty sure it's normal.
