Re: '94 Beretta Z26 trans problem Update #5

I think I finally got it. I located the trans temp wires in the wiring harness by the heater fan motor. I cut the wires and connected them with a 270 Ohm resistor. This resistor value should tell the PCM that the trans is running about 185 degrees. I have driven it twice and it has worked flawlessly...

Re: '94 Beretta Z26 trans problem Update #4

Spent $40 on a used computer from a local salvage yard. Car will crank and fire up for a second but won't stay running. Figured it was a bad PCM, so I went back and swapped it for another one. Same thing: crank and fire, crank and fire, crank and fire but won't run. Dang it. Do I have to get it flas...

Re: '94 Beretta Z26 trans problem Update #3

Got the transmission lines connected to the radiator. Made no difference, still downshifts to 3rd gear after a few miles. Antifreeze and trans fluid are both full. I zapped the steel part of the trans lines near the radiator with a non-contact thermometer, one read 175 degrees, the other read 147 de...

Re: '94 Beretta Z26 trans problem UPDATE #2

A little more info: this car has a auxillary trans cooler on it. However, the trans lines are NOT connected to the factory cooler on the radiator tank. If the trans lines were connected to the radiator, the trans temp and coolant temp should be roughly the same, yes? Since the trans lines are are no...

Re: '94 Beretta Z26 trans problem UPDATE

Got it scanned today, results were Trans Temp Too Cold (110 degrees after driving about 4 miles) and Quad Driver 4 bad. I've done a little internet research but haven't found out yet what Quad Driver 4 pertains to. Am I looking at a PCM replacement? If the Trans Temp is too low, why does it shift co...

'94 Beretta Z26 trans problem

Hello all, occasional reader, first time poster. I have a 1994 Beretta Z26, 3.1L V6, 4T60-E auto, 129000 miles. It was stored(though occasionally started and moved around) after previous owner died. I was told it only needed an intake gasket, figured I better start it up and verify this before I dov...
