Why does the transmission hard shift between 2nd and 3rd gear on a '99 Isuzu Rodeo '98-'04?

Answer 1

I have 2 1998 rodeos and the one with the most milage starts that clunk shifting when the temperature starts getting hot in the summer. In the winter it is not a problem. The other car did this for the first time last week when it was hot and the car sat at the airport for 10 days. It seems to be a solenoid plunger sticking thing. I have not been able to find an answer yet either but I am working at it........ I am having the exact same problem and found this post on another website. Check out the link for a nice set of instructions on how to fix it yourself complete with pictures. Hope it helps. http://isuzufaq.ibctech.ca/range.pdf "I've had a problem with hard shifting on-and-off for over a year. It usually happens only in the morning, and is always after the dash light fails to indicate that the truck is in drive. I had the codes read at a dealer last June, and got back a P0705 code. Is this the range sensor malfunction? If so, any recommendations on what needs to be done and where to get it looked at? I had the same problem with my 99 Passport. I was able to remove my range sensor, take it apart and clean the contacts inside. I remember it was quite dirty and greasy inside. I think they used too much dielectric grease in it, but the contacts were definitely dirty so I cleaned them reassembled it and I have never had the problem come back. The unit is located on the side of the transmission (drivers side) just forward of center. It's been well over a year since I fixed it, but if I remember right to remove it there was a small metal shield that pops off. Then I had to remove 2 bolts and 1 nut that holds the shifter arm and unplug the wire harness (the wire harness was a little difficult to unplug due to the tight space) and the unit will just slide right out. You will need a torx driver to take apart the unit. I wiped most of the grease out of mine; I left some of the grease there so things will slide properly and to keep moisture out. Depending on how dirty the contacts are you can clean them with a pencil eraser or a very, very fine sand paper. Don't spend the 90+ dollars for a new one this is a fairly easy fix, once you see the inside you won't think it's worth the price tag! It should take you about 45-60 min to repair."
