This is on a 87 4x4 Toyota truck and I believe is the A340H auto trans

Problem is it hardly moves when I put it in drive. It's like it's stuck in 3rd gear. I can manually put it in low and two and then into drive and it's fine but it never down shifts

also the Eco and overdrive buttons dont seem to do anything or even light up

any ideas?

Also the fluid level is fine but I have heard it can clog?

Thanks!

 

Bad shift solenoids. Here is a write-up I did a few years ago. Even has links for where to get the new solenoids.

Thanks for the help

 

there's also this... I remember "limps home" so see if you can find that phrase and what is says... I'm just too tired to find it now... But it's in the 1st couple of posts.

Interesting.. I found the "limp home" info, which does describe my situation except that I've not seen my cosole lights on at all (maybe unplugged? no matter what I do they don't light up)

 

It's been a while since I've been in a 340, but are all the solenoids identical including the one in the transfer case? I need to replace all of mine. They are getting really annoying.

 

Had the same problem as you. And I replaced solenoids and fixed the problem

 

Yea I have had issues with mine since i bought mine 2 years ago. I just ordered some off the Makco site, thanks scotty that was a huge help!
