I got the van back the front has a shimmy?

Dont let them pinheads say its not there fault I hear this almost every day and with shoddy work being done in alot of shops these days its always not there fault. When they replaced your tranny they most likely bent a steering arem or misaligned your front end. As for your new electrical problem it could be something as easy as a groung wire that was forgotten to be hooked back up. When they put a new tranny in they pull the motor or drop it out through the bottom. I would take it back and say I want to talk to the manager now and make them fix your van how it was before you brought it in. Dont be bullyied by these dinks. Also contact your better business burea and find out if they have had complaints against them for similar situations in the past. It will most likely boil down to simple stuff like oops need to hook up this ground and dammit why wasnt this vacum line hooked up good luck
