Auto trans issues, need some help :)

[jonahs_supra]

The line pressure is already increased, having the line pressure cable pulled full under part throttle could snap the output shaft or break the 2nd gear Sprag. Leave it adjusted per tsrm..

Wouldnt locking the cable down cause the trans to be hotter?

 

[jonahs_supra]

lol just watched the video
i think you have the "rare" 2spd PowerYota lol

Would different yr trans matter?
What yr is the transmission from?
What yr is car/motor?

Is there any difference between the A340e's from 86-92?

^ 2 speed power glide baby! lol...but I'm not sure if years matter. My car is a 90, the trans if from a pre89. So doesn't that make a difference??

 

[Devin LeBlanc]

The year trans and car should not matter, however there are different castings and model numbers between different years for the valve body's.

I didn't watch all of your video (you took too long). At 3:11 in you are going 70 mph in direct, and you took off in direct. Solenoid number number being off and number 2 on gives you direct. Maybe number 1 is not plugged in. Maybe your harness is bad inside or outside, leading to one staying off, and number 2 staying powered up. Unless you are shifting into O/D later in your video. But I saw no upshift when the conditions were met.

 

[suprafanatic]

All harnesses are plugged in, and all solenoids are plugged in. I have no first gear.

 

[Nick M]

I don't see second either. It is hard to tell with your video.

You should test the solonoids and wiring.
Continuity test with multimeter from the auto computer plugs to the transmission
If you have extra solonoids try swapping one in and make sure everything inside the sump is connected properly (if you haven't already)

But you removed the ect so the above shouldnt matter....
Linkage will make a difference, but if you can count all gear positions using the shifter you should be okay...
I feel your pain, breaking 2 of these and endless problems with a third..
The 3rd had a very similar problem (no 1st no o/d just 3rd and 2nd in L)
I found burnt out wiring behind the ecu and assume it was the problem, but this was during part out

Well Devin is sending me another valve body to try. We think a valve may be stuck.

 

[Nick M]

We think a valve may be stuck.

It might be. Number 1 off and number 2 on will have the same symptom.

 

[suprafanatic]

So you think one of the solenoids may be unplugged?

 

[Devin LeBlanc]

Does not matter if the solenoids are plugged in or not... In L you should have 1st gear, 2nd you should be in 3rd gear and D you should be in overdrive (4th)

There is an issue with the valve body. I have another one almost ready.

Thanks

Good deal, really can't wait to get this thing running right!
