My 98 isuzu trooper check engine light is on. i got it checked and the code reader read that its the fuel injector. i took it to a shop and they went to change the bad fuel injector and when they went in they said that its not the injector causing the problem. they said that something was causing the injector to send off the signal. whatever it is it has my trooper sounding like a diesel truck. do anyone have a clue of what could be causing the problem?

In fact, you can. The large transmission pan has two plugs in the bottom. The higher one is a fill plug. The lower one is a drain plug. The proper procedure for checking the level is: A) Drive vehicle until transmission reaches operating temperature (go for a 30 min drive). B) Park vehicle and apply emergency brake, run gear selector through all gears (engine running, pausing 5 sec.'s in each gear) from Park, down, and back to Park (very important to be in park when checking level). C) Immediately remove the upper fill plug and check level with your finger, it should be just up to the hole, fill as necessary. NOTE: If more than a dribble of fluid drains out when you first open the fill plug then it was overfilled or the procedure was not followed. Use a catch pan under the hole just in case. Filling of the fluid is by means of a small pump and hose, commonly found at auto parts stores.

Be careful............if the engine you want to fit is made by VM, these have individual cylinder heads. In Europe they have given  a heap of trouble and have to be replaced when they overheat.
If you have a friend who speaks Spanish, get him/her to surf  the net and have him/her translate some of the stuff I've read about here in Spain.
I am looking for a Grand Cherokee and have been advised to look for the 2.7 model engine which is a derivative of the older Mercedes engine.........they last forever and spares are easy to get.
