... Here are the codes I'm dealing with.
P0740 TCC ckt malfunction
P0750 shift sol A malfunction
P0755 shift sol B malfunction
P0760 shift sol C malfunction
P0765 shift sol D malfunction
Thanks for the tips. ES, I read about the struggle you're having with yours. I'm not looking to spend lots of time and money on mine either. I think I'll keep looking for a cheap 97-99 Sport to grab out the harness, ecm, and tcm. ....
No worries. I thought that's what I'd remembered you'd done. Yea, understand that. Didn't think you were looking to spend a lot of money on this.
I don't know how well that's going to work, though. There are a LOT of things on the newer Sports that don't exist on the '97-'98 and on the '99. Take a look at my PDF. It runs all the way up into the 2000s; you'll see what I mean.
Those five codes, though, are the ones I was talking about previously. These are triggered when the solenoids - in your case - aren't there. You can wire resistors up in place of the solenoids and that will make the PCM happy. Thankfully, they're not smart enough to know the difference between a solenoid and a resistor. <img src="/forums/images/graemlins/wink.gif" alt="" />

Take a look at my PDF linked to above and look at page 8.
Are these the ONLY codes? No pending codes?
No driveability issues?
BTW, if you stumble across a LS '97 manual harness (both interior dash harnesses, and all the engine stuff, let me know!)
What year and model is your Sport? I wanted to double check that the resistors wouldn't be different.
