Heres the scoop i just recently got this 89 toyota 4runner AUTOMATIC 22re and i love it but it has a problem. When i'm driving it with the lights on the automatic trasmission WILL NOT CHANGE GEARS UNLESS I TURN LIGHTS OFF THEN BACK ON!!!! Its the weridest thing ever. But when the lights are off during daytime driving its perfect only at night when i got the lights on it just will no shift over to the next gear unless i turn the lights off then back on. I though it was the Alt but i don't think it is just that. Any ideas for a blow some money on the ALt lol.

 

Anyone? Auto tranny shifts only with lights off or with them on have to switch fomr on to off to get the tranny to gear.

 

????? hmmm i dont think i can help

bump for someone who knows whats up!

 

Yea its kinda werid i know

 

which automatic trans?

 

I'm not exactly sure right now but the 4runner is a 22re 4cyl ,with manual lockers, and auto main shifter, and 4WD shifter, and shes NON SR5. So not sure maybe i can look her up in a min here...

 

I believe its the A340F though

 

Anyone still got any clue about my werido tranny?

 

340f? are you serious?? wow talk about lazy. Good luck with the SEARCH!!!!!! When you learn how to use it people might be more willing to HELP you with your problem instead of figuring your problem out for you. good luck

 

What? You def made no sense....

 

What part of this did you not understand???? Maybe u should just sell the toyota a buy a heep. It might fit you better

 

Uh not much man maybe you should elabrate more instead of being an azzhole about it. This is my first Auto 4runner and dont know much about auto i've had 3 other past 4runners that were 5-speed. I need help i don't need a jerk off

 

This is not a funny problem its kinda serious to me. When i'm driving down the road switching my lights on and off on and off on and off just to get it to change gears.......kinda sucks and is more less embarrassing

 

If i lived in canada it would really suck

 

Wow over 200 post on here and you need help using the Search function on here???

Ok...... Its at the top of you screen in the light blue bar. It is located in between New Posts and Tread Lightly. If you click on it with your mouse it will almost ask you what you would like to SEARCH.

Also under the search you can click on ADVANCED SEARCH. But given your situation this might be to much for you to handle. So just start off slow with the basic search until you think you can handle the advance search.

 

I can feel the Christmas...

Oh, sorry... Holiday spirit in here.

 

ok sir i did your search and got the same thing i thought it was it is the A340F automatic tranny. So what now? You prolly can't even help me. Anyone know the deal of my tranny.....please let me know before i buy a few things of more expense.

 

Plus i've not found anyone on this site with the same problem. so......gotta ghost in my tranny

 

Is your charging system in gwo? Sounds to me like it's a voltage drop issue. First thing to verify is that you've got good voltage to the transmission control system with the lights on. If voltage is acceptable, then look at the speed sensor #2 and the solenoids.

Is there anything else that goes flakey with the lights on like gauges? Is there any sort of error code? (don't these transmissions give codes through the OD light?

 

First my apologies. After doing a search I seem to only find the 340f listed for the 2.4L. Which makes me wonder why this doesnt make this model a direct bolt in for the 3.4 swap. It also makes me wonder why toyota even but the developed the a340h.

So as to your problem, I would try to obtain a wiring diagram. Could be a lose ground somewhere. I would recommend getting a toyota wiring diagram from toyota and not a haynes or chiltons.

Did you purchase the truck with this problem or did it just start happening?

Can you manually shift your trans with the lights off?
