Eratic transmission shifting vibrates and slips when turning

Though it will not harm your transmission to shift into Neutral while your vehicle is in motion, the additional wear on your brakes by leaving the transmission in Drive will be negligible over the life of the brake pads. It is that minor. NEVER, EVER go into neutral while slowing down to a stop, for 3 reasons: 1.

well you need tranny service.?
right?
did you scan the PCM first to see if there are DTC errors for the trans. seem not and that is first. after.
1: checking levels in box.
2: checking fuses.


older post missed by me.

Sounds like the reverse band or servo has gone out. Transmission shop needed for a confirmation.

1) How's your fluid level?

2) When did you last replace your filter?

3) When it shifted, did it go trough all the gears as you accelerate or did it just stay on one gear and never shifted?

4) How's reverse, does it slip out too after 2 - 3 min?

5) As you first able to shift into gear, you can drive it for 2 to 3 mintues and it just suddenly slip out of gear?


.... could be a number of different things. Maybe even burnt out clutche(s) inside your transmission

there are only 3 issues here.
1 weak engine, , even 1st gear I have no engine power.
2: 1st revs normal but wont shift up.
3: the transmission slips. (flares) RPM goes nuts.

which one?

check fluid level, if good it maybe electrical problem..
check with dealer for recalls

Hello
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

orbital clutches slipping , needs stripping

Vibration at idle brings to mind a few suspects:

transmission mount(s) broken/missing
transmission internally worn
motor mount(s) broken/missing

(1) transmission internally worn or transmission mount broken/missing - test this by shifting into neutral at the next stop light. If the vibration disappears when you disengage the transmission, then the transmission is the source of the vibration. You'll have to inspect the transmission mounts - if they're ok, then the transmission is internally worn and can no longer smoothly "slip" while idling in drive.
(2) motor mount broken/missing - also test this by shifting into neutral at the next stop light. If the vibration persists, then the transmission is exonerated, and the vibration is coming from (under) the engine. The rubber part of motor mounts commonly crack/break and or pop out and are lost.

possibly shift interlock system needs adjustment or replaced .this is a connection between transmission and ignition key lock cylinder . which is why youre able to shift w/o applying brakes and wont start. try to start n neutral.
