Hoping someone can help me here. I recently did some swapping around with my APPS in an effort to rectify hunting in lower gears on my auto transmission. That didn't help the problem and to top it off when I went to turn the truck off after test drive it wouldn't engage in park. Finally got it forced into park and was able to turn the truck off. Tried to start it again and it wouldn't start. I put the truck into neutral and it fired right up.

Little background. Truck is a 99' 3500 4x4 with the 24v. 309k miles on it right now. The transmission was replaced at 137,000ish miles by a private shop. To the best of my knowledge, my ex never did any maintenance on the tranny after it was replaced. So with all that being said, here is my question.

Will replacing filter and fluid on the tranny help? Shift linkage adjustment? Or is the potentially something major?

Hoping none of this sounds too vague. I'm still a work in progress on learning this truck and how to fix everything, but I am trying.

 

I think your shifter linkage needs adjusting. Because as it sits right now it isn't going into park and the neutral safety switch isn't being triggered in park.

 

Thanks so much for your reply! I am in the process of changing the transmission filter and fluid. When I get that all wrapped up I am headed to the neighbors for use of his shop and cooler tools to mess with the shift linkage. Is it pretty self explanatory when you get in there on how to do it, or do I need to do some homework first?

 

Home work is always a plus. I would google it and see about 47re shifter adjustment. And while you are down there check out your TV cable for adjustment too. If that's your issue it will feel like a brand new truck.

 

Headed off to do homework while I drink some coffee. Can't thank you enough for your info!

 

No problem rather it be done right and fix/teach, than it tear up.

 

This may sound like a stupid question, but I have to ask anyway. Are the basic mechanics the same in a transmission for a 3500, as say they are in a 1500? I found a pretty decent write up on what I need to do here, but its for a 1500.

 

I would say yes

 

Hey Ghostman. Hoping you are around today. Finally got to the front band adjustment on my truck today(long story). Finally got the locknut loosened, and now I have what I think may be a problem. The adj screw doesn't want to get tight. It wants to feed all the way down in the locknut with no stopping point. I only backed the locknut off a couple turns before attempting the adjustment because the adjustment screw was spinning freely. The only thing that I think I may have screwed up on is not holding the locknut as I tried to tighten the adj screw. Is that my problem here, or is it something else?

 

I think the spade may have fallen off the adjustment stud. or the band is worn out.
Not to worry both can be fixed here are some pictures of what i am talking about.
Is your pan off and valve body removed?

does the adjustment screw look like this?



this is a normal picture of a good band.



this is adjusted way out



Hopefully your band still has some material on it and it doesnt look like this.



Here is a picture of the end of the band with just the pan off.




Not to worry it can all be fixed without pulling the trans let us know what you find and we can help.
