'91 loyale automatic shifting problems

[mrairrikk]

very new subaru guy here.

a buddy and i bought a 1991 subaru loyale wagon with an automatic tranny, we had to swap in a different engine, from a parts loyale we got too, anyways, after finally getting it up and running, we relaized the transmission wasnt shifting when it was in drive, but it shifts fine manually.

i heard rumor there is some kind of module on the outside ofthe trany that goes bad and can be replaced easily. is this true ?

 

any ideas what could be the problem ?

 

the fluid level is correct.

 

thanks for any help.

Is it a 3 spd auto. If so I have the same problem. Put it in drive and it

 

starts from a dead stop in 3rd gear. It doesnt shift down into 2 or 1. But if

 

I moved it manually it would shift. I cleaned the govenor(search for that)

 

and replaced the vacume modulator(just below the govenor). After driving it

 

a lot the tranny has gotten better. When it warms up it actually works

 

pretty well. Until it warms up it still doesnt shift out of thrid when in drive.

 

Im told you can take the oil pan off the tranny and clean it out as well as

 

the screen filter. It is suposed to make a world of difference. Just run a search and you will find alot

Both these problems sound like electrical. Did the wires get disconnected when the engine got changed over?

 

The second poster should check for trouble codes from the transmission. His car sounds like it's in limp mode.

On my car there is no check light on or anything. How do I check to see if it is in "limp mode"

Thanks

Check to see if you reattached the vacuum line that runs from the intake down to the vacuum modulator. If the line is attached and there is oil inside it, the modulator needs replaced. About the only other thing is the governor is bad. may want to do a search for "apple core".
