I had my manifold gasket replaced at a shop 2 years ago. Then I did alot of repairs and upgrades myself with ASE certified friends. Im gone on the Great Lakes ships usually 5-10 months at a time. I dont get to drive much. Over the last year or so Ive noticed my truck studders if Im hard in the throtle @ the shift points. Once or twice from 1st to 2nd. Then really bad going from 2nd to third. Its like it has a governer or cant decide if it really wants to shift. The other day I was looking under the hood doing a tune up and noticed this (photo below) thing said on the top part "Bottom" Should I flip it over? One of the hoses goes to the front of my throttle body , two seem to go to my front end, and the other is a larger diameter and goes down below where the driver is to the rear. (its a 4x4 96' dodge 1500, 360ci engine) Ive been to many shops before and they cant figure out why it wont shift properly. I had the trans rebuilt by a professional shop and they still are at a loss as to why.

Pic of the item, not sure what it is. The Haynes manual only has two things it might be. An EGR item or part of the EVAP. Please help. If you read the picture after clicking on it, youll see it seems to be upside down.

Thanks in advance for any help.

 

That's the Evap Purge Solenoid.

 

Well I have no idea as to what its called but mine is mounted the same way as yours. Sorry can't help there.

As for the hard shifts, on the left side of the Throttle body is a cable that controls the transmission pressure and you can move it slightly to increase or decrease the shift. I moved mine for a longer more solid shift with hard throttle.

Thanks 97black Ram. Im gonna go check that out now.

 

That is the evap purge solenoid. The tube connection on the "BOTTOM" side is labled VAC and should go to the throttle body. The one closest to the "TOP" or "UP" is the vapor line from the vapor canister. The solenoid end is suppose to be on top but should work as long as the lines are connected right. Probalby less likely to stick open if its mounted upright. If you take it off you can gently blow into the tube connection on the solenoid side, if any air passes thru and out the VAC side its leaking and needs cleaned or replaced.
