What years auto transmission fit a 1999 4X4 Isuzu Trooper Limited w/TOD power/winter drive?

USA spec car ? y/n?
ISuszu, maker. , 3.2 or 3.5Liter engine? or the DIESEL then?
2wd or 4wd?
6VE1 engine GAS, DOHC? twin cam? the tranny is not the same on all. is why I must ask, or the VIN code.
internal leaks on all old transmission get worse HOT as ATF thins hot.
A Borg-Warner torque-on-demand ("TOD") all-wheel-drive system was introduced then.
or GM box.
4L30E four-speed automatic. The 4l30E was fitted with both a "power" shift feature allowing the gearbox to take better advantage of the engine's power by adjusting the shifting nature and a "winter" mode permitting third gear starts for added stability in slippery conditions.


SCAN TOOL 101 USA car, right?
THE OBD2 PORT, DLC PIN 16 MUST BE at +12VDC OR THE FUSE TO THAT PIN IS BLOWN IN any USA CARS.FUSE BOX. FOR SURE.
TRY KEY ON TEST. PIN 16. volts.

THEN USE A SCAN TOOL REAL , 2008 OR NEWER.
NOT A $17 CODE READER JUNK A REAL SCAN TOOL.
RENT ONE?
let me see what is really there first, engine ,,trans and comms

the side of transmission has a side plate tag telling what is there.
the 4L30e box is TCM electronically shifted.,
the TOD box is 4wd only. Torque on DEMAND
The TOD indicator is visible on the left-side of the instrument cluster and displays a progressive indication of torque application, using 3 bars, got that/
see pin 8 jumper trick, for TCM error codes. document ions is rare
Yes 4L30E are solenoid shifted
and if speed sensors fail the TCM has no way to shift right.

A/B kit is 2 parts
the 5 SOL kit is $250

FIND THE SHOP MANUAL, BUT ARE SUPER SUPER RARE.

old car, no operators guide.
is car 4wd??? must be
is car autotmatic, seem so....
google broken today?

omg, its there,

found this info: "The available 4-speed automatic features a winter mode. When it's engaged, the transmission starts out in third gear to prevent wheelspin on icy or snowy surfaces. The transmission also has a power mode that gives better acceleration by raising up-shift points. Both modes are controlled by well-placed pushbuttons in the center console."

all with google or DD in 5 seconds work,,,,,

lots of Rodeo parts on car. and this.
The vehicle also features the Torque on Demand (TOD) 4-wheel-drive system produced by BorgWarner.

seem like you need to find a TOD and 4speed expert.
why not scan the PCM to see all those transmission errors.????
check fuses first.
yah, yah , nobody scans here. just guess.

This indicated that some problem in transmission gearbox or gearbox harnees

There is nothing wrong with the system. When the TOD is in auto it will only engage the front wheels when the rear wheels lose traction. Newer small SUVs have just the opposite, they are in front wheel drive until they lose traction and then engages the rear. Isuzu was ahead of its time with the TOD system.

It may not have a switch, check your owners manual.

The transmission doesn't have a dip stick you will have to take some where and have them check it, unless you feel comfortable doing it your self. The power steering on the other hand. If you pop the hood look around you should see a black cap that says powersteering fluid, when you take the cap off it should have a dip stick attached to the lid if not there will be a fluid level mark on the side of the tank, which you took the lid off of.

look at vsv assembly related posts on this site. Wesley has a great procedure. Works!!

get a code reader and see what codes it pulls

Power drive delays the shift points for upshift of the automatic transmission. It will degrade fuel economy, but you'll get more peppy performance.

Winter drive will only engage if the vehicle speed is below a certain threshold (I think 23 miles per hour) - and only if the vehicle is in Reverse, Neutral, or Drive. It causes the automatic transmission to start off in 3rd gear (rather than 1st gear). The purpose is to provide power, but not torque to the tires. In winter driving, torque increases the probablility of the tires spinning. The vehicle will seem to be VERY sluggish when winter driving is engaged - which is completely normal behaviour. It will automatically disengage when vehicle speed increases above the threshold.
