Transmission issues with 5 codes

1997 GMC 1500 5.7 4l60e 141,000 miles

The first of trouble is when I started up my truck, there was no tach, no speedometer, and the truck would only start, and stay in 2nd gear and reverse. I bought a code reader, and made it home. After getting home I truned off the truck, let it sit for about 45 minutes and started it up and the tach, speedo worked, as did the transmission (statred out in first).

Here are the codes:

P0740
P0753
P0758
P1860
P0740

Should I rely on driving my truck as I drive 60 some miles to and from work if this is a hiccup?

RE: Transmission issues with 5 codes

PO740-Torque converter clutch enable solenoid circuit

PO753-1-2 shift solenoid circuit

PO758-2-3 shift solenoid circuit

PO1860-Torque converter clutch pulse width modulator solenoid circuit

PO740Same as above

This ain't no hiccup, dude, check your tranny fuel level, check your fuses, and see into having the transmission looked at if it's not something simple causing your shift solenoids in your tranny to stick like this.

That's "check your tranny fluid level" sorry.

Thanks for the reply. I'm starting to hear that the ignition switch is probably the source issue....weird enough...

Nah, that actually makes a lot of sense to me, I had an F150 which caused me no end of grief over the ignition switch being out of alignment, if you moved the lock cylinder an extra 3/8 of an inch, half the options like the A/C, wipers, all turned on. It's a heluva lot cheaper than tranny problems. Hopefully you're right.

I cleared the codes yesterday afternoon. I drove about 10 miles yesterday-this morning combined with no ill effects. I have yet to verify the wiring underneath.

Hopefully I will get a chance to do so later this afternoon.

Welcome to the forum...
the shift solenoids are located within the transmission, once the pan, filter and fluid are removed the solenoids are located at the rear of the valve body assembly... (4L60E)
