#51 of 59 2002 Rodeo LS 4x4 O2 Sensor and tranny issue by justanox Aug 25, 2009 (7:07 am)
I've got a 2002 Rodeo LS 4x4 with 74k miles on it and I was wondering if you Trooper guys can help. I'm getting a P0141 code (O2 sensor heater circuit, passenger side post-catalytic converter). I've replaced the sensor, erased the code with a scan tool and I'm still getting the CEL!   I've also had an issue with the Trans running 4th gear at high rpm (2900 rpm 60mph). If i push it past 70 mph, the tranny clunks real hard and the light comes on. This happened previously this year and I had to replace the tranny. When the truck gets to 60mph, the rpms jump a little then settle back in. I'm thinking wiring issue but no one can figure it out.   has anyone run into this that's had a Trooper? The Rodeo forum hasn't provided any info yet.   thanks!
#52 of 59 2000 Trooper auto trans works in manual mode only PLEASE HELP by kather Sep 15, 2009 (8:50 am)
I took out a loan for $1700 to have my transmission rebuilt. I have a few issues, most of which I think have a lot to do with my being a single 50ish female. The shop that worked on my car has been extremely evasive and abusive about everything that's gone wrong ever since the work was done. I truly believe that the shop took short cuts, and perhaps are not well-versed in the transmission problems of a 2000 Isuzu Trooper LS. I NEED WHATEVER FEEDBACK I CAN GET to identify the realities of my situation. I must find a job asap, and I need my car!!. One of the first interesting things I read was that my car has a sealed transmission, which needs to be replaced, not repaired. Is this true? Secondly, the shop that did the work considers anything electrical in nature that may be causing the problem to be outside of, ie: not included in the price of the work they did. Is this common, acceptable practice? Also, another mechanic (very recently) showed me that 5 of the pan bolts were stripped and therefore would not achieve the necessary torque. In one of the pan bolts the original mechanic had placed a wire in the threads in an attempt to have the bolt tighten against it !! Not only had the original mechanic not advised me of the problem, but what he did say was that he "fixed everything he came across like new". Within a couple of months the car wasn't shifting properly, was out of fluid, and when I had asked the original mechanic what the problem had been he snapped at me that "it blew a seal!!, it happens!!" Is it considered acceptable prac- tice to rebuild a transmission without making sure it all bolts back together properly? The last time I took it to the original mechanic, the transmission would only shift manually. The mechanic insured I didn't go anywhere else by insisting I leave my car that moment, while taking 3 days to tell me that it was an electrical problem, HAVING "NOTHING TO DO WITH THE RE-BUILD". He gave it back to me saying the repair cost $140.00. The transmission worked for about 10 miles, then reverted back to manual-only operation. When I called the mechanic, he yelled at me that it worked when I got it, and when I asked him what had been the problem he fixed, he said he fixed a burned wire, and further yelled that he "could spend all day explaining it too me but I would never understand!!" I didn't go back. I did, though, have two other mechanics look for any trace of a burned or recently repaired wire, and there was none. I have since done more research and learned that the electrical system needs to be "reset" following a rebuild. Maybe he doesn't know about that? I also read in my owners manual that the NEED FOR MANUAL OPERATION IS A MODE THAT THE COMPUTER SETS THE CAR INTO WHEN THE TRANSMISSION IS NOT WORKING PROPERLY. Through all of this the original mechanic has been telling me I only had a 90 day warrantee on the work, but when I pulled out the original invoice, it said 12 months.   The mechanic that showed me the stripped bolts also pointed out that what trans fluid was there was burned. Does that necessarily mean that the tranny needs to be replaced/repaired again? I have been driving the car manually, but only around town, no more than 35mph. Can that alone burn-up a transmission if there is fluid? Or is the overheating directly related to the leaking transmission fluid?.   I have 30 days left on my 12 month warranty, but I don't want to go back to these guys without some ammunition. I have already filed a report with Fl Dept of Consumer Services, which I'm told is supposed to regulate business practices. When the trans shop finally responded, they said two things: my model of "transmission is re-buildable, and the transmission works fine." DCS did nothing and closed the file. I contacted the Attorney General, and they answered back that it was the DCS I had to speak to. I can't believe that NEITHER of them has addressed my very specific complaints. All of the other mechanics that have seen the car say that I need to take the car back and demand that they do it right, but I have absolutely no confidence in that idea, and no confidence in either the ability or integrity of this shop. I've already come very close to loosing my home. I have to get a job right away, but I live in a smaller town, with very few open positions in my field, at my salary range.   I welcome any input that may help me put this to rest.

Wow! It sounds like this mechanic is a piece of work. I hate when people don't take responsibility for their work. Honesty is so hard to come by with mechanics these days. Obviously this mechanic also lacks social skills if he can't be courteous with you. My suggestion is make sure you document every bit of communication and work that you have with them with dates/times. You can also consult an attorney. Some attorneys will even write a letter on your behalf with your expectations to the repair shop. Just having it on legal letterhead may add some persuasion that they need to get it in gear and help resolve the issues they've created. You might also see if one of the other mechanics you've spoken with will go with you to the repair shop and have a sit down with those guys. That way you can have it all laid out for you and the mechanic you bring with you and can call BS or ask questions if things are unclear right there on the spot. Again, document everything. The only problem with trying to take another mechanic with you is that it might be taboo to do so...since they are competitors. But doesn't hurt to ask. Offer them some cash for their time. It may be well worth it. You can also talk to your local news agencies (TV and newspaper) to see if they might help you set things right if the above doesn't work. Our local TV news has a segment where they confront bad businesses on consumers behalf on the news. Good luck. I know it is frustrating. I just took my 2000 Trooper in yesterday to begin having it's transmission rebuilt today. I am hoping they are an honorable shop. The Better Business Bureau gave them an A+. That reminds me...you can file a complaint with the BBB also. Replies to this message: kather (Sep 17, 2009 6:35 am)

Replying to: heykennedy (Sep 17, 2009 3:48 am) Thank you so much for taking the time to read my long message and respond!. I have found a low cost atty service, they're next, and hopefully more readers will respond, especially transmission mechanics, so that I can show technical as well as consumer responses to the atty. I was hoping the Dept of Consumer Services guy would stand beside me on this, he even told me on the phone that he would keep pushing until we got a satisfactory response, then the next thing I got was his letter completely dropping the ball. Believe me I've thought alot about paying one of the other mechanics to go in with me, but they're in another city, and likely to consider it too much an imposition to begin with. And I have contacted a couple of "investigative reporter" scenarios, but they have either not responded or brushed me off with a form letter. Thanks again for your support, a little outside empathy goes a long way for me these days. KatheR

Replying to: mapfish1 (Aug 13, 2009 8:49 am) My buddy had the same problem. We jacked it up  and checked to make sure the drive shafts to the front hubs were turning, they were. We pulled the wheels and the snap ring on the right front was broken. Replaced the 16 cent snap and the drive on the front worked.

#59 of 59 94 Trooper OD problems by lslaluz Dec 02, 2009 (8:26 pm)
My 94 trooper with 235,000 miles recently had the transmission completely rebuilt after the original tranny finally went out: new clutches, torque converter, valve body, solenoids, the whole nine yards. After the rebuild, everything worked fine except cruising on the highway in OD. When not deliberately on the throttle, the car would shift from 4th back to third with high rpms, until i pushed the accelerator again. The transmission shop has worked non-stop for the past 3 weeks, going back through, disassembling, reassembling, replacing all solenoids again, vehicle speed sensor, throttle position sensors, wiring, etc. After weeks of combing through everything again and again, we are at a loss. The car works fine, except in Overdrive on the highway. Any thoughts?
