Output speed sensor on the trans might as well. (if you have one... not sure on that.)

 

I thought the cruise control had nothing to do with the transmission? mine doesnt work either never has...

 

It doesn't. Aside from pcm reading trans output speed for the cruise..... (or, just vehicle speed from whichever sensor, according to year of the truck.)

Trans and cruise both pay attention to the brake switch though, trans will unlock tcc when you step on the brake, cruise will disengage.

 

Yeah I do have have the speed sensor and did change that yesterday. It was a cheap part so I figured what the heck. No difference at all. As far as the CC not working its not a big deal since I rarely use it but obviously the OD is another matter entirely. Other than making me paranoid as hell about my trans it's killin me running over 3k rpms on interstate. Gas mileage is bad enough as it is...


Auggiedoggy when I hit the OD button the OD lite comes on and goes off like its supposed to when you hit the switch but no change in rpms at all. It has no noticable affect at all.
I will definitely check ebay for some of the parts, thanks for the info.
Not sure about the 02 sensor but may try switching them and see what that does. The 02 code is very sporadic, doesnt do it every time I drive it and the CEL will stay off for a day and then pop up the next. Not sure if the PO gutted the cat or not but honestly it looks like the exhaust has never been apart. Exhaust is one of the things I wanna take care of in the near future because mine is the original and its seen bettter days. No leaks that I can tell yet but looks like it wont be long. And I'm very paranoid about the cat clogging up after reading some of the posts here. If it is the original cat and hasn't been gutted then it has 166,000 on it....

I will also have to check out the brake switch. Is there any way to test it without hooking up a scan tool? I may try to go have that done in a few. Would the scan tools they have at Advance or Autozone tell me what I need to know? (I'm not that knowlegeable at scan tools. I use the key trick to check the CEL and haven't used scan tools much..)

 

I'm sorry to say, but, in an earlier post you said you found a piece or pieces of a snap ring in the pan. That is for the OD unit. You may able to take the OD unit off and have it fixed rather than having the tranny rebuilt. As far as the rest of the issues go, ie CC. I wouldn't bother with that until the tranny is fixed.

 

You could take a volt meter or take the switch off and use an ohm meter...but you would probably have to have a wiring diagram to determine what your checking, but i think that switch is cheap...may be easier to just replace it.....just a thought..

 

Replace the switch all you want, that snap ring is the problem. And it won't be long before the TC implodes also.

 

Well I'm hoping the impending TC implosion will hold off just a little longer. Hoping to find a trans to rebuild myself so I can get this taken care of. Might have a line on a trans out of a 96 with 100,000 miles on it....cheap! If I can get that and a rebuild kit, new TC etc then hopefully this issue won't be a problem but until then I guess I'll keep trying to figure this one out. At the very least it's an educational learning process.

 

You will have to update all the electronics in the 96 trans. But, that will be part of a standard rebuild in any event. I think the valve bodies are different though.... or, at least, the part the governor pressure sensor/solenoid bolt to..... I think that part just bolts onto the valve body in any event though... so, a relatively easy conversion.

 

HeyYou...are you psychic? I was just researching the differences between the 96 and the 01! Damn ur good!
