2002 4x4 Excursion Transmission question
I have used this truck to tow a 34' 9600 lb TT. Currently has 118k on it. Towing probably constitutes 15% of the mileage. I have towed the last 2 weekends with strange results. 1st weekend was to the mountains in NC but I was only towing a utility trailer with a four wheeler on it. I never noticed any problems until we stopped to drop the four wheeler off on the return trip. I had towed about 200 miles when we stopped. After dropping off the four wheeler the truck would not drop into 1st gear. (it is an automatic BTW) I tried to manually move it into first and second and it wouldn't go into either (IE, the lever moved correctly, but the transmission acted as if it was in high still.) I turned the truck off and back on and the problem went away. The transmission temp gauge was reading in the middle like always.(I do not have an aftermarket gauge)
This past weekend I hooked up the camper to go to the beach. As soon as I started down the drive way the I noticed the truck wasn't in low. Went through the routine again (shifted to 1st and 2nd then turned the truck off.) Same results. Shifted fine after that. Worked fine the rest of the weekend. BUT, I have a 2 week trip to Florida planned for this June. So, I am wondering if there is something I should be doing now, to try to find a potential problem.
The last time I changed the transmission fluid (at 90k miles BTW) I used Mobil1 ATF. We do NOT put a whole lot of miles on this truck. (Been almost a year since I changed the fluid and we took a long trip right after I changed the fluid last spring)
Any suggestions or ideas? I am thinking I may do another transmission fluid change IF I can find the right transmission fluid (I read a post somewhere that Mobil1 has changed their ATF to be Mercon V) Past that I am not sure what else to try.
Thanks in advance for any suggestions,
