Randomly goes VERY slow on acceleration

[temps425]

Randomly I will go to begin moving and there is no torque, the engine revs high but moves very slow w/ no torque. Almost like its trying to start in 2nd gear (auto trans) When it does this, the Overdrive light blinks on and off.

It does it when warm, cool cold, when first driving, and after driving a long ways. I will do it for 1 start, or 5 starts. There is NO consistency WHATSOEVER that I can find.

VERY strange to me...trans oil clean and tranny shifts very good all the time over wise. Anyone else experienced this?

sounds like the "slip" in "yer tranny's slipping"

When it does this, the Overdrive light blinks on and off.

blink means it's in trouble...hence, it's called a trouble code. How it lets you know its got a code is the O/D light blinking. You'll need to visit the FAQ to know more. I'm not a AT man.

The handheld code reader doesnt show anything or is not working right. What is the best way to pull a code? Thanks

Just found this.......1992 4runner auto
https://forum.ih8mud.com/79-95-toyota-truck-tech/243559-1992-4runner-tranny-surging-3rd-gear.html

INFOs
Automatic Transmission

Looks likes it's gonna be a 3.0L

Is the tranny a;
340E
340H
340F
I'm to lazy to find out the difference.

TEMPS: Check the "diagnose system" section on each one.

somethings not right...?


IIRC, you don't even need a code reader to get the code, for that model....

Should just be a paperclip. What ports, IDK.

Transmission solenoid #1 replace

Turns out this is the tranni solenoid #1 cutting out. Does the tranni have to be pulled to replace it??

 

[2ndGenToyotaFan]

I don't believe so... I think they are all accessible with the pan off... But I'm no expert!

 

[temps425]

Cant find anything regarding this in the manual and I've never gotten into the tranny solenoids before. Anyone know more info on this??

 

[2ndGenToyotaFan]

Check out the factory service manual linked in the FAQ thread here. I think it's for a 93... but should be pretty similar.

Take a pic of the vin plate on the door jamb and post up, need to find out what tranny it's got...... though I suspect it's the A340H.
