Hi,

I'm hoping someone can offer some advice. I'm working on a 2011 Jeep JK with a 42RLE transmission. I bought it with a P0868 and a P0218 code. I dropped the pan and the fluid wasn't burned or low. I changed the filter and solenoid pack, reassembled and replaced the fluid. I took to the top hot line when it was hot. The Jeep has always ran, drove, and shifted normal but has codes so it won't pass emissions. The P0868 returns after clearing in about 20 miles and the P0218 about 50 milesw after that. Nothing appears to be running hot but I don't have actual fluid temps. Any input would be appreciated.
