There are several reasons that made cause an automobile to lose power going up a hill. The most common reason is a lack of fuel, caused by a plugged fuel filter.
your transmission is going out
The synchros are going out on the tranny
If it's knocking it's probably a rod going out - if it's ticking it could just be the valves - Rodeos are notorious for value noise...
Could be low fluid,a bad sensor or transmission going bad.
a bad seal will result in fluid loss, which will cause tranny issues. If its from fluid loss, its a seal, if The fluid looks reddish and the filter is within mileage, the tranny is probably going out. JayWalt coooldude@ilovejesus.net
Mine did that about a year ago it was low on transmission fluid so I would try going to your local repair shop and having them check it out. It may also be your shifter solenoid, which goes out on these transmission frequently.
You are probably going to have to replace the wiper arm. Go to a good salvage yard and get one off a decent looking wreck.
This totally going to depend on the maintenance it had previously. With good care the engine should out last the body. With poor care it could go any time.
A code 37 on an Isuzu Rodeo means to check the transmission. This could mean that a short is occurring between the Transmission Control Module and the Electronic Computer Unit. Check all wires going from the transmission to the computer. If no short is found, a tube might be placed over the wires to prevent them from accidentally coding for no reason other than magnetic interference.
The transmission is not shifting in and out of gear or your front joint is going bad
Check for a broken motor mount or transmission could be going bad.
I am presently going through the samething. Try changing the trans fluid and filter, it is most times recommeded after 100,000 miles.
