Greetings Planet Isuzoo! I come in peace … and with a question! :)

I would very much appreciate help identifying the appropriate vehicle for the transmission described below - refer to images attached of green plate and solenoid connectors.

Short version of a long story…

After the transmission failed in my 2001 Isuzu Trooper, I purchased a replacement tray from a remote seller. The seller claims it is compatible with my vehicle and was an inventory item that had never been used.

Initially the transmission appeared to be the real thing. However upon installation, my mechanic discovered that the electrical connectors are drastically different. Additionally, the holes for the connectors were casted with different diameters preventing a simple electrical swap. I have confirmed these issues with a local transmission specialist who concluded this 4L30E was not made for and will not work with my vehicle.

I would be very much appreciated if anyone has experience with other vehicles possibly pertaining to this transmission. So far, we have not found the tray part number in either GM nor Isuzu databases. The local specialist suspects this was made for a BMW.

Thanks in advance for any assistance!

Purchased Replacement Transmission:
Part number (green tag) - 96018004
Serial number (green tag) - 5754116
Front solenoid connector - Round 5 wire connector
Back solenoid connector - Square, 4 wire connector

In case it helps… here is a comparison with my original tranny:

Original Transmission:
Part number (green tag) - 96018507
Serial number (green tag) - 5912323
Front solenoid - Square, 4 wire connector
Back solenoid - Round, 7 wire

Just to repeat, my original plan was to bolt this transmission on and go. With the electrical connector and solenoid differences, this is not possible. Furthermore, the casting sizes are different for the connector plugs, so my transmission specialist is unable to swap electronics or otherwise modify. I would appreciate any thoughts as to what vehicle this tray was made for.

Your vehicle does have a 4L30E trans however, the replacement tranny sounds like a BMW tranny. While they are the same, in my recent research I found that the sensor configuration is completely different. I would return it and keep looking.

Good luck!

Thanks Mike,

That was exactly what my local transmission guy was thinking. Is there anyway to confirm by cross-referencing the part number to a BMW part number? It may even be worth more as a BMW tranny. :)

The problem I am having is that the seller is sticking to the story that this transmission was made for an Isuzu trooper - even after talking directly to the transmission guy that has looked at both of them.

I hope this has a happy ending.

That looks like a pre-grade logic Isuzu transmission from a late-90s truck. Here's the pic of one from a 99 Rodeo:

Note the short harness on the range switch, vs the long harness on the muddy trans at the bottom which is a stock 94 Trooper 4L30E. Those connectors on your replacement seem to match what was on those two vehicles. I can't comment on the connectors on the newer grade-logic 4L30E.

What does the green tag on the side say?

I am attaching a close-up shot of the green tag.

There is also a white sticker that has a bar code that is labelled:

"GM Hydramatic Strasbourg France 96018 004" <bar code> "*5754116RFL*" which corresponds to the green tag part and serial number.

It's possibly from a '98-99 rodeo/amigo.

RODEO....TRANSMISSION ASM; AUTO....8-96018-004-3....07-1997 to 08-1999....A/T THM....4X4
AMIGO....TRANSMISSION ASM; AUTO....8-96018-004-3....08-1998 to 08-1999 ....A/T THM....4X4

Your Trooper uses a Pulse Width Modulated (PWM) torque converter which requires a transmission with a PWM compatible hydraulic pump and PWM TCC solenoid installed. My info indicates only 00-02 Isuzu Troopers and maybe 02 Isuzu Axiom had this type transmission.

The case connector is a 4 pin on 6 cylinder vehicles 90-99, and 4 cylinder 90-01.
The case connector is a 7 pin on 6 cylinder vehicles 00-up, and 4 cylinder 02-up.

The overdrive case connector is 5 pin on 6 cylinder vehicles 90-99, and 4 cylinder 90-01.
The overdrive case connector is 4 pin on 6 cylinder vehicles 00-up, and 4 cylinder 02-up.

Since your replacement has the wrong connectors for a PWM compatible transmission, it won't work even if you rewired the connectors.

I don't think you have one made for BMW,unless they swapped bellhousings thinking no harm, no foul. if you look on the bellhousing you can see where the starter mounts up is down about 70 deg or so and that's the right spot for your motor. The 4l30 made for BMW has the starter 15 deg or so from the top. At least on my car (92 e34) and in e36s, and Z roadsters.

THAT TRANS IS FOR A 98-99 RODEO, AND WILL NOT AS BUSTER SAID WORK IN THE TROOPER
HOW EVER IT WILL WORK IN THE 99 BACK THUR 93 RODEOS AND WILL ALL SO WORK IN THE 99 AND EARLIER TROOPERS ,BUT IN 2000 THEY CHANGED THE DESIGN OF THE CONNECTORS AS YOU HAVE FOUND .

Thanks everyone!

Any ideas why the part number cannot be cross-referenced in the Isuzu (nor GM) database? Neither the transmission specialist nor other companies could find it. Is it possible this was not even intended for an Isuzu based upon it the part # not being registered with Isuzu?

ALL YOU DO IS ADD AND 8 TO THE FRT OF THAT PART NO AND AT THE END A 0 1 2 OR 3 DEPENDING ON WHEN IT WAS PRODUCED , IT WONT SHOW UP AS A GM PT SINCE GM =NEVER USED THAT TRANS IN A DOMESTIC VEH, IN THAT VERSION IT WAS ONLY PRODUCED FOR ISUZU .U.S EVEN THOUGH THE STRASBURG PLANT MADE DOZENS OF DIFF MODELS , ,FOR CADILLIAC , BMW AND A COUPLE OTHER CARS , THEY WERNT 4WD , EVEN THE 2WD ARE NOT THE SAME TRANS , EVEN ISUZU USED 3-4 DIFF VERSION, BMW USED A 5PSD VERSION OF THAT SAME TRANS , I PUNCHED IN THE PT NO AND ADDED THE 2 EXTRA NO,S TO MAKE IT AN ISUZU PT AND IT CAME UP AS A RODEO, ,NOTHING SPECIAL ABOUT IT , THEY GAVE YOU THE WRONG TRANS

How come Isuzu didnt get a 5 speed variant? Other than cost was there a legitimate reason?

THREE THINGS , THE 5SPD ISNT THAT OLD A MODEL ,FAIRLY RECENT , COST IS ANOTHER ONE, AND THE 5 SPD ISNT AS STRONG AS THE 4 SPEED ,BECAUSE OF THE WAY THEY SET UP ONE OF THE PLANETARIES , A MUCH BETTER SOLUTION WOULD HAVE BEEN THE 4 SPD A/ WARNER MUCH BETTER GEARING AND MUCH STRONGER TRANS AND A LOT LESS POWER LOSS .

It looks like my transmission! How much did you pay btw? Just in case I have to get one for my truck someday...
The seller stated this was an old inventory stock item when he used to run a transmission shop. I paid 1K plus the freight cost from California to Texas. I am certain he would be glad to sell it to you... not many "new" trannys left.

I wanted to thank everyone again for the help! The saga has a happy ending, the seller is taking back the transmission and re-imbursing me my original costs.

Meanwhile - my original transmission has been rebuild and I am back on the road. Transmission specialist rebuilt the original tranny as a 2 valve as opposed to the 4 valve I had. He said the 2 valve configuration is much better. Perhaps it just needs to "break in", but the shifting does not seem as smooth as I recall.

Happy Thanksgiving everyone!
