P0700 + P1738 two years after transmission rebuilt
Hi all,
I am noticing the CEL blinking 10x on start. Other than that, not noticing any other issues.
Codes show:
P0700 - Automatic Transmission Control System
P1738 - 2nd clutch pressure switch
The transmission was rebuilt almost two years ago. It is under warranty [4yr/50,000 miles]. I plan on calling the shop. Since I no longer live near the shop, I wanted to ask here if this is something that could be minor and will be less time and gas/toll money to check it out myself? Does this seem like something that the shop could fix in an hour if I brought it down there? Or is it likely a drop off for the week and I am looking at uber and checking train schedules to get back home. Obviously no one can say for sure based on the little info I provided, but was hoping for a little insight. Plus, I haven't bugged anyone here in quite some time... which reminds me is that Milwaukee Dave guy still around here

P0700 means that there are one or more A/T DTC, unrelated to fuel or emissions control systems.
As for troubleshooting, grab a multimeter and try this:
* Check voltage of 2nd clutch pressure switch (blu/blk wire, female terminal). Should get battery voltage. If not -> broken wire between PCM and 2nd clutch pressure switch.
* Check resistance of 2nd clutch pressure switch (male terminal).
Chances are you need a new pressure switch. I don't have a '99 so I don't know exactly where it is, but it appears to be on the top of the trans. Good luck and let us know how it goes.
