i actually ordered valve seats mistakenly, was trying to find a list of stuff to get done at that same time as valve springs. the seats were only 10$ so if you one of you wants them you can have them. i'll toss em in an envelope, i'd be surprised if this truck gets anymore than a few thousand miles a year on it.
This is what an exhaust brake looks like. It mounts right behind the turbo and I
can see you do not have one in place.
The part you showed in your initial post is this-
That is the spool valve that activates the brake by sending vacuum to it. If you have an automatic, you need a converter lockup controller for the exhaust brake to actually work. It has a separate 3 position switch, which locks up the torque converter when the exhaust brake is activated so you aren't losing all the braking effect in the converter and overheating the transmission. I don't anything about the 47RH so I have no idea if there is a lockup controller for them or how different it would be from a 47RE controller.
The lockup controller looks like this-
If you aren't towing anything heavy there is no reason to really have it.
thank you! i was trying to identify the thing with the bd sticker on the left side of the trans in my photo. i have the spool valve installed so i'm sure at some
point my pops had an exhaust brake, i don't think its there anymore though. Going through this thing trying to see whats been done / what needs to be done
