Ok, I've got a wierd problem and I'm wondering if you all have some insight.

If I let my truck sit for a day or two, she won't move. The engine is purring, the transmission shifts fine, but the tranny case seems to be stuck in neutral. I can shift it from 4 lo, 4 hi, 2 hi, nothing.

If I let is run for about 10-20 minutes though, it works just fine. I can shift between 4 lo, 4 hi, and 2 hi like it was brand new.

Does anyone have any idea why this is happening and how to fix it? Is it a pressure thing? Does the tranny case require pressure to work? I'm admit I'm over my head, which is why I'm hoping you all have some great insight.

Thanks!
 
what kinda tranny you got, auto or manual. seems to be your tranny not the Xcse. the Xcase is all gear driven, not hydrolic. can your Xcase lever move back n forth through the 4lo-N-2Hi-4Hi shift pattern. check the tranny fluid when cold and when hot.

the above assumes you have an auto

Cool another pacific northwesterner, try and fill out your profile a little more , like what year your truck is and what tranny and transfer case (if you have one) you have... /forums/images/icons/cool.gif That will give us a better understanding of what you might be dealing with.../forums/images/icons/wink.gif
 
arq,

My tranny is an auto. and yes the Xcase lever can move back n forth through the pattern no problem. I'll check the fluid, that seems like it would be the simple answer. I was thinking that it was a problem with the Xcase since it seems to be engaging the engine when I shift it.

I'll let you know.
 
Yup, lovin' life in the forests, mountains, and beaches. Can't beat the NW.

I honestly don't know for sure what I have for a tranny and Xcase. The guy I bought it from barely knew it was a blazer when I bought it. It's been a serious guessing game up to this point as to what is really on it. Is there an easy way to identify what I have?
 
yea, go to the tranny shop and tell them you need your tranny fixed/forums/images/icons/smile.gif. if the guy is nice he will tell you what you have under there. while you're at it ask him what kinda Xcase you have/forums/images/icons/smile.gif

front
4LO
N
2HI
4HI

it's most likely a th350

but then again i am just guessing. what year is your blazer??

Heh. I told ya I was a novice, but that's why I bought her in the first place.

Xcase is definately at NP205, and I think it's a TH350, but again, I don't know for sure, but it fits your description. It's a 1970. Picture is at http://rooba.net/K5.php.
