Well where do I start. AAMCO transmissions as a whole does not have a very good reputation, not to say there are not some good ones around. They are a franchise and anyone with some cash can open one regardless of how much tranny experience they have. They advertise comprehensive training but thatÆs mostly business training and not technical training they are expected to hire experienced people to do the work. Not a single one here is still in business. They say electrical components (ôsö, more than one) are fried (shot, burned up) Sounds like it shouldnÆt even be running at all, but it was and probably not all that bad except that you had you had to turn the engine off to reset the computer every so often. Your tranny is (was) going into limp mode which is a classic sign of a low voltage problem. Another thing that bothers me is that they say ôpoor design for cooling in Rodeos/Passports/Pathfindersö not once have I heard anyone say anything about poor cooling in these. Not to say they have the best system. These are trucks have decient towing capacity and are great off roaders which can put demands on the tranny, so keeping it cool is a must, heat is the #1 killer of transmissions. I wonder if they were just talking to sound like they know what they are doing. One thing IÆve learned is the people on this site are very, very good at troubleshooting and fixing problems with these trucks, better than most Isuzu dealers and certainly better than most independent shops. Not because they are better mechanics but because they see the same problem over and over and over again. There are not enough of them out there nor can people afford to take them to the dealers about the only time they see the same problem over and over again is for recalls. I still think I didnÆt need to replace mine as soon as I did. But I plan to keep mine for a long time so I donÆt I donÆt feel quite as bad. My $3000.00 tranny was actually a brand new one with all the current updates, it has no dip stick. There was a bunch of these new ones around 5 or 6 years ago I found a place on the web selling them but you had to buy like 100 which is how I think my tranny shop got one from their wholesale parts supplier. IÆve read a couple posts that talk about rebuilding these and they say it should cost around $1500.00 and I would think R & R should be no more than $500.00. IÆve got a 4L30E out of a 90 Trooper I could sell you, but it probally would cost you around $600 to buy it and get it pulled and shipped. Its in a trooper I bought for parts. The vehicle has 120k on it, but I have no idea what kind of shape the tranny is in so I wonÆt warranty it.. The vehicle got broken into and the dash trashed trying to hot wire it, which is why they scraped it. Since you already have yours out I think your better off having yours gone through and put back in, but I think you should shop around. You might put a post on here asking if anyone knows of a good tranny shop in your area that has experience rebuilding the 4L30E. If you do decide you might be interested in my used one let me know.
