Hi, I don't know think there would be a relationship between the two events, but these are directions for performing the fluid check. As you discovered, there is no dipstick. I have posted a picture that the directions refer to at : http://www.carspace.com/atfdmike/.59a349cd!v= Be very careful when working under a running vehicle. You should chock the wheels to insure it will not move while underneath it. I hope this helps you.

Vehicle Level Maintenance Fluids Fluid - A/T Testing and Inspection
Testing and Inspection
CHECKING TRANSMISSION FLUID LEVEL AND CONDITION
Checking fluid level and condition (color and odor) at regular intervals will provide early diagnosis information about the transmission. This information may be used to correct a condition that, if not detected early, could result in major transmission repairs.
IMPORTANT.- When new, automatic transmission fluid is red in color. As the vehicle is driven, the transmission fluid will begin to look darker in color. The color may eventually appear light brown.
A dark brown color with burnt odor may indicate excessive fluid deterioration and signal a need for fluid change.
FLUID LEVEL
When adding or changing fluid, use only DEXRON (R) -III.
CAUTION: DO NOT OVERFILL. Overfilling will cause foaming, loss of fluid, abnormal shifting and possible damage to the transmission.
Park the vehicle on level ground and apply the parking brake firmly.
Check fluid level with engine running at idle. NOTE: Be sure that transmission fluid temperature is below 30 °C (86 °F).
Move the selector lever through all gear ranges.
Move the selector lever to "Park".
Let engine idle for 3 minutes and open the overfill screw (1).
Add released ( this means proper grade) transmission fluid until it flows out over the overfill screw opening.
Let engine idle until a fluid temperature between 32 °C (90 °F) and 57 °C (135 °F) is reached, then close the overfill screw (1). Torque: 38 Nm (28 ft. lbs.) NOTE: Check transmission fluid temperature with scan tool. Minimum fluid level 57 °C (135 °F) Maximum fluid level 32 °C (90 °F)
CAUTION: Do not open overfill screw with engine stopped.
CAUTION: DO NOT CHECK FLUID LEVEL UNDER THESE CONDITIONS:
Immediately after driving at sustained highway speeds.
In heavy city traffic during hot weather.
If vehicle is towing a trailer.
If the vehicle has been operated under these conditions, shut the engine off and allow the vehicle to "cool" for thirty (30) minutes. After the cool down period, restart the vehicle and continue from step 2 above.

#3017 of 3299 92 Isuzu Trooper - Steering wheel vibration 45 - 60 mph when turning by kirkdc
May 03, 2006 (11:52 am)
Replying to: atfdmike (Apr 26, 2006 5:14 am)
I am experiencing a strong vibration in the steering wheel when turning the steering wheel on my 92 Trooper between at speeds between 45 - 60 MPH. The ride is relatively smooth when driving straight ahead. The vibration also goes away at speeds over 65 MPH. At speeds under 45 MPH there are no issues. Does anyone know what can be causing this problem?
#3018 of 3299 Internal corrosion in coolant system by cptsesso
May 09, 2006 (12:31 pm)
Anyone here experience this problem with a newer vehicle?I have a 2002 Axiom with 49,900 miles. Sunday, while driving to work, temp gauge shot up to beyond hot. I immediately pulled over and shut it down. Smoke coming from under hood and coolant level was near empty.
I had the vehicle towed to the dealership where I purchased it and they found a coolant line, which passes under the intake manifold, had ruptured. The line had eroded from the inside out and was full of "gunk" as they called it. They asked if I used the vehicle for towing, which I did not, and then suggested I probably did not follow the required maintenance schedule.
I have all service records which prove I have done the maintenance, but the 3yr/50k warranty had timed out 6 months before. No problem I thought because at their urging I had purchased an extended warranty through CNA, which I was told would cover everything except normal wear and tear items for 10yr/120k. Wrong. They will not cover this coolant line.
Now this is going to cost me almost $500 to make this repair and I don't have any idea if the overheating may have damaged the engine further. It starts up and idles perfectly, but who knows what might have have been stressed during the overheat.
Has anyone ever heard of corrosion forming that severely after only 3.5 years and 49k miles?
Any thoughts would be appreciated.

If you didn't flush the coolant at least once in that time, it's possible. But then, does your maintenance schedule require this to be done within 49K? If not, one wonders how they could accuse you of neglect. If it does require it and you didn't do it, well then....... Anyway, you're out of warranty so the question is really moot I think, unless you can dig up some kind of recall issued on this problem.
If you shut the engine off in time, you should be okay. Your quick reaction might have paid off. Hope so.

I was wondering about your extended warranty. Usually there is a toll free number for the company issuing it, found in the paperwork you received with it. Have you contacted them directly or is it just the shop's decision that the problem is not covered? Might be worth asking the warranty company itself. Also, the intervals for coolant change are every 30,000 by the manual, but does it specify that in your owners manual?Again, it might be worth looking at, and if you had it in for any service at or prior to around 30,000 miles, a good dealer should have brought it to your attention if it needed to be done. Hope your luck gets better.

I had the coolant exchanged at 30k. I can't remember what the manual calls for as I do not have it in front of me right now, but I did have it done, so it was probably called for. As far as the ext warranty company, the mech at the dealer said he called them and they denied the claim saying it is not covered.
I am going to pick it up tomorrow and will have a nice little conversation with the sales manager who said all would be covered except wear and tear items.

May 16, 2006 (4:05 pm)
Hello GroupWow what a great forum to find..
Hello Group
I am the proud owner of a 1991 Isuzu Trooper (6cyl). Recently I have smelled gas while driving.Sometimes when i stop i also smell it.It seems to be coming from the rear however..no leaks, and not all the time..i replaced the fuel pump 2 years ago..the smell is quite concerning..
any suggestions? someone told me it could be a faulty gas cap..could this be a cause?
he gas smell comes into the cab..also we can smell it near the rear of the truck
Thanks

Hi, I hope you are going to check your fuel system thoroughly. I suppose it is possible that the fuel cap might vent, but it is not supposed to, as to keep hydrocarbons out of the atmosphere. I would be very concerned if you smell gasoline at any time besides fueling up. By way of background, you have a pressurized fuel system from the pump to the injectors. That mean while the engine is running, and for 2 seconds after the key is turned on, the fuel pump is making about 35 to 42 pounds of pressure. If it is leaking into the frame, top of tank, skid plate, etc; you might not find any dripping evidence on the ground, especially if it is a tiny high pressure leak. Once you assure yourself that the integrity of the fuel system is OK, IE: tank itself is not leaking (check inside of fuel tank skid plate if equipped) along with above, then you might inspect the emission system. Follows is the factory manual description that might help you. The six cylinder engine has the same basic components. Good luck and let us know how you make out. EVAPORATIVE EMISSION CONTROL SYSTEM
A closed fuel tank ventilation system is used to prevent evaporative hydrocarbon emissions from escaping the fuel system into the atmosphere. Fuel tank vapors are stored in an activated carbon (charcoal) canister when the vehicle is off and vented to the intake manifold to be consumed when the engine is running.
Here is a link to a diagram to show what the system looks like under the hood and the fuel tank:
http://www.carspace.com/atfdmike/.59a44ffa!v=
http://www.carspace.com/atfdmike/.59a4501d!v=
Check hoses for kinks, cuts, deterioration.
The ECM controlled canister purge vacuum switching valve (VSV) is in the vacuum line to the purge control valve. Normally closed, the VSV opens when energized by the ECM. During idle or cold operation, the VSV is closed (de-energized), preventing canister purging. The ECM energizes the VSV to permit canister purge only under these conditions:
Engine at operating temperature.
Engine must run for a specified length of time.
Vehicle must be operating above a specified road speed.
Throttle must be open more than a specified angle.

Vehicle Level Powertrain Management Fuel Delivery and Air Induction Fuel Tank Service Precautions
Service Precautions
WARNING: Adhere to the following procedures any time the fuel system is being worked on in order to reduce the risk of fire and personal injury:
Keep a dry chemical (Class B) fire extinguisher near the work area.
Place a "CAUTION FLAMMABLE" sign in the work area.
Work in a well-ventilated area. Do not smoke, and keep sparks and open flames away.
Wear eye protection.
Use caution when working near the catalytic converter to prevent the possibility of burns or fire. (The temperatures within the converter can exceed 537 degrees C (1000 degrees F).)
Relieve the fuel system pressure prior to disconnecting fuel system components.
Disconnect the negative battery cable except for tests where battery voltage is required.
Use a suitable container to store or catch fuel.
Do not replace fuel pipe with fuel hose.
Plug all disconnected fuel line fittings and hoses.
After making any fuel system repairs ALWAYS inspect for fuel leaks.
Replace all pipes with the same pipe and fittings that were removed. Do not reuse "O" rings. Always replace.
Do not attempt repairs on the fuel system until you have read the instructions and checked the pictures relating to that repair.
Adhere to all Notices and Cautions.
NOTE: If available, use system bleed valve (schrader) to relieve pressure.
NYLON FUEL PIPE CAUTIONS: In order to reduce the risk of fire and personal injury observe the following items:
Replace all nylon fuel pipes that are nicked, scratched or damaged during installation, do not attempt to repair the sections of the nylon fuel pipes
Do not hammer directly on the fuel harness body clips when installing new fuel pipes. Damage to the nylon pipes may result in a fuel leak.
Always cover nylon vapor pipes with a wet towel before using a torch near them. Also, never expose the vehicle to temperatures higher than 115°C (239°F) for more than one hour, or more than 90°C (194°F) for any extended period.
Apply a few drops of clean engine oil to the male pipe ends before connecting fuel pipe fittings. This will ensure proper reconnection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.)
