Source for Solenoids

[Mac]

The automatic transmission on my 1988 Comanche is not shifting into 2nd or 3rd.  I think I need to replace the 3 solenoids the filter and gasket.  I belie3ve the transmission is a AW 30-40LE but not sure.  Does anyone know a supplier who has these parts.

 

Thanks,

Mac

83504044(x1 needed) and 83504043(x2 needed) are your solenoid numbers. Catalogue doesn't say which is which

Filter kit is this number: 5083122AA. Don't know who Chryslers supplier is. Probably Aisin or Warner as it is a joint project between the two companies for AW4.

check them first, continuity and see if they are not stuck...

Other than the solenoids, what else could be causing the problem of not shifting into 2nd or 3rd?  Do I need to worry about the TCU?
