"First, thanks Dnult for your help throughout this project. I am posting these results so that others can refer to it in case they experience the same problem.

The problem: 97 4sp Auto 4L60E Transmission, Service Engine Soon Light came on, then transmission started shifting funny. It would start out in second and only shift to third. No first and no overdrive.

The cause: Bad Shift Solenoid. I went to Autozone to get a free OBDII reading and they told me the code was P753 - "Shift Solenoid "A" -- Electrical." When a shift solenoid goes bad, the transmission goes into a "limp-home" mode which is the 2-3 shift only (and that one shift seems to be kind of harsh....).

Autozone doesn't stock the shift solenoid but the dealer did. AC Delco # 10478131 $19.18.

I had to take the transmission pan down to reach the solenoid so I also got the supplies to change the fluid and tranny filter while I was in there. It helps to have a very large drip pan so you can catch all of the fluid --There is no drain-plug. You just have to remove the bolts and let the fluid spill out. There are two identical shift solenoids ('A' 1-2 shift and 'B' 2-3 shift). I pulled them both --be sure to take out the retainer clips on the bottom and then disconnect the wiring harness) With wires, I jumped them off the battery to locate the bad one - the good one clicked the bad one did nothing at all -- easy to spot!! The filter pulls out without any tools -- in the hole where the filter comes out, there is a metal/rubber seal -- take that out with a screwdriver carefully so you dont nick the tranny case. Insert the new seal and filter. The new solenoid went back in the same way it came out. I cleaned the gasket surfaces on the pan and tranny and bolted everything back in place. It takes about 6-7 quarts of Dextron III fluid to refill through the dipstick-tube if you change the filter. I started the motor and put the tranny in and out of all the gears several times to "bleed" everything down there. Mission accomplished! It works perfectly -- Special thanks to Dnult who gave me guidence throughout this project! You Rule ! ! ! !"

Got it off of a different forum, but hopefully it helps you out. I've done a couple of these they're not too bad if I remember correctly. This is a good description of how to take care of this, and hopefully get you back on the road!

I would change both shift solenoids.

Be careful with the back edge of the pan and contact against the solenoids if space is tight around a crossmember or exhaust pipe. You can break the solenoids

Yes, same applies.

You may have found this old thread in a search, the info is still valid, though.
