'94 Rodeo A/T probs. Computer?

[rodeo02]

Oops! I take that back! The 1998+ DO have "L" for 1st. Just got out of my 2002. PRND32L staring me right in the face for the past 4yrs .

But I'm really good about never having gotten mud or anything of the likes in the engine bay.

Question for you, how many miles would you say you got out of your radiator? I'm trying to decide if I should just go ahead, for safety sake, and change it out this summer - it does have 153k. I do have it flushed every year, but we have a Toyota truck that the 1st radiator had a blockage at 199k and blew the headgasket, taking the engine with it.

Then the 2nd headgasket blew on that same truck just earlier this month - so we're a bit paranoid with the Rodeo in not wanting the same fate.

I'm the original owner and it's never overheated, and I have the tranny flushed every 30k miles. Wish I had more faith in just dropping the pan, and doing it that way, but I'm a bit leary of not adding the right amount.

How often do you drop your tranny pan?

Ha! I said the origional owner washed it weekly... From me it gets the SimpleGreen about once a MONTH...

If I remember correctly, I started having overheating probs at about 200-210K... But it was a gradual thing... I only noticed it at low speed/heavy load. Either pulling my trailer in heavy traffic, or climbing the Main Divide (dirt) Road in the Santa Ana Mtns. (I had just made a run to the River with outside temps way over 100, and the A/C on all the time, and had no problems at all, even pulling the long grade out of Needles, but then I was running 70MPH+) When I finally took it to a friend who has a radiator shop, he just had me run it for a few minutes and turn it off... Then he just reached in and ran his hand across it, and about half or slightly more, was cool to touch. (The area on the return side... He said that it was a build up of the silicate (?) that settles out of the regular (green) style coolants as it dumps back in.) (Be SURE you turn it off first... ;-)

I've only done the tranny filter twice in the three years now that I've owned it... It would be do again, but I'd like to change ALL of it this time... Is that something that has to be done at a shop?... It sounds like it.

I put a volt meter to the battery this afternoon, but I'm not sure of the reading... I'm reading 16.1V, and that seems way high, so I want to check my son's truck in the morning and see if my meter is out of whack. (It read the same running or off, BTW.)

I didn't think to check and see if there was a voltage loss if I checked Pos. terminal to the chassis or to the engine block instead of just checking post to post... I'll do that in the morning...

Good morning... I thought that I had replied to this last night, but I guess it's lost in cyber space... I'll start again.

HA! I said that the ORIGIONAL ownew washed the motor weekly... From me, it gets the Simple Green treatment once a month or so... And I DO try to keep to the 3K-4K oil change schedule... (I got the lifetime free tire rotation, so I get that done too.)

Regards the overheating... If I remember, it was at the 200K-210K range, but it was gradual... It only "got-hot" at LOW speed and HEAVY load. The first time I was pulling my trailer inheavy morning traffic... Outside temps in the 60s... Next day, I was trying to get up a long steep ridge in the Santa Ana Mtns.

A month earlier I had made a trip to the River with outside temps over 100, and the AC going all the time. I had NO problems, even when pulling the long grade out of Needles, but I WAS running 70MPH +. (That's why I thought that the clutch fan was the prob. and didn't think about the radiator... well, that and the fact that the coolant looked just SO clean! Sorry, Amigo_2k )

I have only dropped the tranny pan twice since I've owned it... It would be due again but this time I'll have it flushed, I guess... Where does one go for that?

................

I tried to check the voltage yesterday but read 16.1V, (running and off), so I think that my meter is out of whack...

Ok... Got a better meter on it and, yes, I am showing 14.25v, running. Note that there is NO voltage drop checking to a chassis ground, or to the engine block, rather than directly between the pos. and neg. posts...

Off now to get some new Battery and ground cables... This should be fun, the ground cable runs into a loom and off to who-knows-where!

I'm not sure that I know where to start... ;-(

Ok, so you're saying if the inside (next to the engine) of the radiator is cool to the touch after driving, then it's most likely plugged?

Reason I'm asking, is I've reached in to check my Rodeo's radiator a time or two after a pretty good highway run, usually 10-20 minutes after shutting it off, and it'll be mostly cool to the touch.

I haven't checked it immediately after it shutting off, so I've just assumed that it's cooled off pretty fast.

Don't have any overheating issues; it never goes past the half-way mark.

Hi there... It WAS immediate and the temperature zone was like a triangle... From the top corner where the water returns, diagonally down towards the opposite corner of the radiator was cool... The other half was too hot to hold your hand on.

For me, the temp gauge never got past the half way point either, until I put a heavy load on it (towing/climbing) at very slow speed.

.....................

OK... I replaced the neg. battery cable and cleaned,checked and added two new ground straps, and I DO have 14.29v (that is up from the earlier 14.25v if that means anything)... There is NO voltage drop when I ground to the engine, chassis or tin, and I don't show anything but zeros when I check the chassis/tin/engine/tranny with an Ohm meter. But I STILL have the flashing "Check Trans" light and no shifting...

What next?

Did you check the amp on your alternator under load?

These trucks are funny about their volts.

Good morning...
OK... You'll have to help me out here?

No I just checked the volts: 14.25 BEFORE I cleaned and checked everything... (But it DID read that across the two battery posts and also from the Pos. post to the Engine/chassis/tin. NO voltage drop.)

Then I pulled 14.29v after I replaced the ground cable and cleaned everything up... BTW... I have no idea if that .04v means anything.

I did NOT put it in gear to pull down the engine, I'll go do that now.

I had never had ANY signs of trouble until I disconnected that dang battery a while back... Isn't there a just a way to hit Ctrl/Alt/Delete and re-boot the computer?

Good morning again... In low with the parking brake on, I'm getting 14.32v this morning... Same flashing "Check Trans" light and still in, what seems to be, "winter mode", i.e., it wants to take off in 3 unless L is selected manually.

Thanks,
Jim

Does ANYONE make a code reader that is compatable with this truck? (OK, and less than $500 or so?) I have been all over the web and can't find any that purport to be Isuzu friendly...

I'l like to try just "clearing the code" now that I've cleaned up all of the body ground stuff...

Is your battery a maintenance free?

Ok, so you're getting 14volts, but is that at the battery or the alternator?

No... I add water every so often.

Checked with a itsy-bitsy RadioShack multi-purpose meter right at the battery posts.


... and I just checked it with all the lights and AC on and it drops to 13.99v -14.04v as the AC cycles.

JM- It looks like your battery and charging system are 100%. Look into the transmission range sensor. LOTS of posts on this. Search for 'range sensor', 'mode sensor', 'TRS', etc...

OK... Thanks for trying...

Would there be any advantage to trying to "clear the code"? I hear that there is a way to do that with a paperclip, but I'd hate to short the wrong plug!

Any response to my question about a code reader for this rig?

Again, Thanks all... !
