What a mess batery and tran prob

Sometimes when im driving my trooper the check trans light comes on and i lose most of my power. took it to a mechanic, said it was an electrical prob and that the transmission was fine. if you pulled over, turned the car off, then turned it back on again the light was gone. the tranny problem went away on its own for some time. all summer in fact but now that its getting colder the light comes on everytime i start her. another thing happend at the same time which led me to think it may still be electrical.. my battery started to sizzle and it is toast now. im not so good at wrenching, don't even know if these problems are related or maybe jesus just doesn't like me and my whole trooper falls apart at once. i certainly need help though, any suggestions?

    i have the same thing going on with my trooper! in the summer it was fine, but now in the winter its doing that to, most the time when it moves gears from 1-2 and sometimes 2-3 and when i put it in R, but the light comes on and it lost its power!

2001 Isuzu Trooper 4wd automatic trans. It will shift ou of 1st at about 20 mph into 2nd then loses power, rpm's drop until it slows to about 10mph then down shifts back to 1st. Any ideas why?


Sounds to me that your transmission is put itself into what is call (Limp Mode). This happens when the transmission fluid in the trans hydraulic valve body located on the bottom and in the trans pan are not within the parameters of the transmission computer. You can remove the trans pan and gasket to check for metallic material in the bottom of the pan. There is normally a strong magnet in the pan catch the material so I can't move freely through the transmission itself. It only takes a very small piece of foreign material to stop the flow of the valve body fluid. I would first take it to somewhere that had a automotive diagnostic scan tool that can read transmission codes to see if there are any active codes. Next you can drop the transmission pan yourself and look for material in it. Basically do a visually inspection and service the transmission fluid, gasket, and filter. Remember, all a automatic transmission is a extremely complicated fluid pump. If its pumping trans fluid properly it's probably working just fine. Been when the trans fluid gets hot, scorched, and stops moving. It will not work. Hope this helps

It could be as simple as you don't have enough trans fluid. It could also be a shift actuator/solenoid. Have you checked the level of your trans fluid?

Hi my 'check trans' light has come on my isuzu trooper


check to see if the fluid level is right. I have not encountered a car with that light but if that light is in fact what you say it is that would be the easiest thing to check.
