Hello everyone let me start off by saying my 2003 Avalanche has 290k miles. I bought it 5 months ago it's a 1 owner never in an accident. The transmission has slipped since i bought it and have recently got around too having my mechanic entirely rebuild the transmission for $1300. Considering im having an electrical issue it's worth noting that it has an aftermarket stereo (has worked great no issues). and the driver side door lock actuator has not worked. I replaced it and it didn't fix it. I thought it had a short in the driver's side door and didn't want too mess around with the wiring as it does not bother me too much having too use the key too unlock the door. (Not sure if this has anything too do with anything but) I have got the "Battery not charging" message since i bought it and have learned too ignore it when it periodically comes on. My mechanic has checked the battery many times and alternator is brand newish so its not that. 200 miles after driving with my new transmission i have noticed the transmission would slip into 3rd when going about 70mph and sometimes just would not shift back into 4th at all unless i stopped using the vehicle for 20-30min. Check engine light was on for the shift solenoid D and Transmission fluid pressure switch. after a few days of using it here and there the transmission lost all gears except park (Thank God I was at home) my mechanic came over and dropped the pan, replaced the Transmission fluid pressure switch, put the fluid back in, told me too start it up and put it into gear. I had a working transmission again! 2 days after that today i get the check engine light again for the same code. So im pretty sure whats going too happen next... im scared too drive it now that its acting up again. Fuses relays are all fine i checked them first. I really want too fix it the plan was too keep it forever and ever i have wanted an Avalanche ever since I was a little boy and im so sad that i can't even drive it im beside myself just thinking about maybe having too sell it. dont know what too do now or what too look for if you have any suggestions at all on what too do next PLZ leave a comment.
