Ugh more problems

[Nosparkplugs]

Truck in signature with 165 000 tuned to stock.
1 When i let off the brake going into Reverse it sounds like i am letting off a clutch. It pulls down the engine to about 450 rpms and sounds just like a manuel. It does this about all the time but not when its cold. It only does it going into reverse not drive. It actually sounds pretty cool but im sure its not good. I guess if it is trans related i am way over do since this is the original trans. Everyone ive talked to gives me a funny look on this one so im depending on the org
2. Much less important but i put in a new fuel drain and am still leaking fuel (not as much at all though) but i cannot trace down where exactly i was wondering if there were any other common places.
3. After i get 1 and 2 done i am in need of new 4x4 stickers. My dad dropped a bale on the bed and when the body shop fixed it they never replaced the stickkers so i would like to see some cool ones you guys got.
Thanks a lot in advance you guys are always helpful

Bump anybody?

[chrismjennings]

My pickup just started doing the same thing, in reverse only! It is probably not going to be a good outcome, but i would like to hear the diagnosis. So somebody please reply.

[chrismjennings]

did this problem start after the (CPS) sensor was replaced? because i just had mine replaced about a month ago and now i am having this issue.

[Nosparkplugs]

No i put mine in a while ago. It did happen after i put in the new drain valve lol. i doubt that had much to do with it though but who knows. Doesnt sound like a common problem though

[chrismjennings]

Well hopefully somebody knows something!
