4x4 and chip question

[95_Powerstroke]

So I have a 1995 F-250 4x4 auto and when I try and engage the transfer case it is extra extra hard and requires lots of force and frustration to get it to change between 2 Hi, 4 Hi, and 4 Lo. It also seems like they are not in the right places if that makes any sense; it appears like it is in 2 hi but the 4x4 light on the dash is still on, if I keep pushing and wiggling it will eventually click forward and the 4x4 light will go off. And after all this, the 4x4 does still work from what I can tell. Should I just service it or is something wrong with the transfer case? I was planning on servicing it this week end anyway. Any help/info/advice would be greatly appreciated.

Second question concerns a chip. My brother bought a 2001 F250 a few months back and it came with a tuner. I'm not sure what type at this point but I will find out. It has 3 settings, economy, tow, and extreme (I think) and he bought a new DP tuner so I was wondering if this chip would work for mine or if I would need to have it re tuned. If you guys think it'll work, I'll take it off his hands and use it until I can afford my DP tuner, I just don't want to hurt my truck.

Sorry for the long questions, thanks again for any help.

That's strange with what's going on with your transfer case. I can't help you there. Your other question, if it's actually a tuner, it will plug into the OBSII port. Your truck being a 95 it won't work, That is a 96 and newer port. Even if it's free, you'd be better off buying a chip since you have an auto.

Both the DP Tuner and the chip from my brother are actual chips that go into the PCM. I realized after i posted this though that I forgot he has a 6 speed so it will not work anyway. Oh well, thanks anyway. Still would like to figure out this transfer case issue. I do not want to waste the time or money servicing it if it is toast haha.

I don't want to state the obvious, but I had a very similiar problem with my 97 F350. I soaked all the linkages underneath in Krol Oil (penetrant/lube), I'm sure any would work, and now I can shift it with no issues at all.

That chip won't work in your 95,sorry.

Thanks, I'll give that a try and see if it helps.

@bucwheat thanks for the response. I'll just wait and get my DP instead

Agree on the shift lever. Lubricate it and check it over to make sure nothing is bent or binding.
