I'm sorry you are having problems with your vehicle. I will try to help.I'm a full time mechanic and have been a mechanic for over 20 yrs and I work part-time here on JustAnswer to help you and others repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as neeed, even after the rating.. I will need for you to be my hands and eyes since I'm not there.Is this only happening in drive? If you select 1st does it go into 1st or only second?I strive to provide 5 star service. If I have satisfactorily answered your question please rate it as such and hit submit. Doing so is the only way I get compensated for my time. Also it doesn't close the discussion so we will still be able to communicate if there are further questions.

It's unlikely the epc as it would either shift hard or have trouble in 2nd as well. But it could be the 1/2 shift solenoid or the clutches.
Customer: replied 22 days ago.
Every other gear is fine
Expert:  Master Auto Tech. replied 22 days ago.

Customer: replied 22 days ago.
Code 28 Transmission Range Switch Error
Expert:  Master Auto Tech. replied 22 days ago.
Sorry My data system crashed. Give me 20 or 30 min to get it back up. So I can look up a few more things. But it's looking more like your shift solenoid or clutch pack. How does it do in reverse?
Customer: replied 22 days ago.
Reverse is perfect also. Like I said. All gears are fine, it just starts in 2nd, so it feels like a slip. Code 28
Expert:  Master Auto Tech. replied 22 days ago.
Ok. Let me get my system back up
Expert:  Master Auto Tech. replied 22 days ago.
here is the test procedure for code 282. Test the transaxle range switch operation during the test drive.3. Test circuits at the TR switch. C1 7 cavity connector terminal B ignition power. C2 4 cavity connector terminal A Black/White wire A, terminal B Yellow wire B, terminal C Gray wire C, terminal D White wire P. Voltages should be B+ or 0.0 volts.4. Replace the transaxle range switch.What you should see on ea wire.Tech Tips: The transaxle range switch is mounted on the transmission on the shift shaft. The inputs should be:
A 12 volts in P, R, D, 2.
B 12 volts R, N, O.D., D.
C 12 volts O.D., D, 2, 1.
D/P 12 volts P, N, D, 1.Now with all that, I've seen that cause no shifts and no over drive or tcc lockup but not usually no 1st. But I'd start with testing it and replacing if needed
