Just purchased this at a very low price. 141,000 miles, 8.5 interior, 7.5 exterior. I have it running great except for the tranny (Auto) will not shift on it's own.. Manually it goes through the gears fine. I'm assuming a shift solenoid??
You Guru's taught me a lot before my purchase! )Lurking here) Hopefully you will have sound advice!

I'm assuming you're correct! No paperwork but title to verify. I think the engine has ITEC on it somewhere and this is

the shifter. 3 speed with an overdrive button.

Yup thats the 2.6 with the auto! Very rare and dependable trans (note my signature lol). If only Isuzu stuck with Aisin Warner for the autos in the US market instead of GM... what could have been. PM me your email and I can send you the AW30-80LE troubleshooting manual.

This one is specific to the trans and goes much more in depth. I'm surprised it uploaded

Is this available for downloading? I have a 1989, and this would sure be a lot more helpful that the nothing I currently have.
I tried to upload it on here and it wouldn't let me. But I think it will send via email.

No, all I get is an attachment of the front page cover image. My email is [email protected]
I sure would appreciate you sending it to me. I been pretty successful with most electrical issues, but schematics sure would speed things along.
I sent it
