Tranny-vacuum modulator

[Gintaka]

Okay I've narrowed my transmission problem down to the vacuum modulator, and I have no idea where it is or what it looks like. I have a '92....can anyone help me with this? Is the modulator near the transfer case?? Thanks in advance

Rone, E4OD's do not have a vacuum modulator.

What is the problem?

C6's have a vac modulator which wern't available on half ton trucks in 92+

Ok, I took my truck to 2 different tranny places and, like you said, I dont have a vacuum modulator. So it is a transmission problem for sure. They hooked it up to an electric thing and estimated the repairs at $1650, with a 2 year warranty. Does that sound right to you guys? How do I know if my truck has the E4OD or the AOD? whats the difference? I have overdrive on the end of the shifter...thanks

Push button is the E4OD in 92.

What is the tranny doing?

&, did they tell you any DTC numbers?

Is Autozone in your area still doing DTC checks? or DIY; post back w/info that A just asked + more.

Ok the tranny guy replaced a little plastic, flask-looking thing that attatches to the outside of the tranny, he said that it tells the transmission wich gear it should be in; its an electric deal. That fixed the problem it seems so now I have a tranny with 145,000 miles on it with no problems!!!! Thanks for the input guys.
