Hey guys. I had my brother in law take my Jeep to the shop yesterday (local Jeep dealer) because my check engine light came on last week. The light went off the day after it came on. I didn't get the code it threw, but he said I'm going to need a new Transmission Shift Module. I'm not sure what that is, or even does. All I know is he said it is an $800 part. He said he didn't think it needed to be done immediately, but I'm looking to see if anyone else knows anything about it? The Jeep seems to be driving fine, and I haven't noticed it shifting any different than it ever has. Hope someone knows something lol. Thanks.
