now im not a mechanic,but im pretty sure my tranny is electronic solenoid shift(my z34 is a 91)so im thinking if it was rebuilt and they did a good job(no offence)it could be your #2 solenoid?as for testing it:confused: not sure how.
these other guys on here can give you more info
(i have been wrong before,im not perfect)

ah ok and where on the tranny is the solinodes if you know? ya the tranny was a rebuilt from a GM Good Wrench so i dunno

so how can i test it does anyone know? and is there a diaganostic tool like the OBD2 but for 95 and older cars to read the sensors so i know whats all going on so i dont need to take it to a dealer or so and hook up to a diagnostic machine anyone have was of making a cable and hooking to the computer and see it on the laptop like the fuel pressure etc?

when making or buying a usb or serial to OBD1 connection and use a laptop with software will it tell me what solinode is not working?

also what software will work with a lumina? 3.4 i havent seen one really
