So my engine recently went out and I don’t have a lot of money to spend on a brand new engine(quoted $12k) or hardly a used one, so I’ve been searching on eBay and found a used engine, same as the one currently have, with about 56k miles for about $2,900. My jeep is a automatic 2013 jeep wrangler Sahara and it currently has a 3.6L V6.
Well I talked to the seller and he said his was a 2012 manual, now I’m not sure if he was talking about his own personal jeep or the one it came from. He was talking like it would work and that he’d like to talk to my mechanic about the engine and to “be on the same page” in his words.( I am not saying anything bad about him, he was very sweet) I ended up sending the engine to my grandfather and he said he didn’t believe the deal and that he wasn’t sure if it would work because of the different transmissions.

I need a mechanics or someone who works on cars/ knows cars help because I don’t want to call my mechanic and ask what I feel may be a stupid question 😭

So I bought my first jeep, 2015 JK with 105k miles on it. It’s on a 2.5 lift with 35’s, few days after purchasing it a had a crankshaft sensor go, annoying but no biggie easy fix. I don’t do a ton of off roading, but I have noticed even going up minor hills just driving that once or twice the temperature gauge went a little past the half way point then backed down after letting off. My guess wants to say that it wouldn’t hurt to install an inline transmission cooler which I would imagine would put less stress on the rest of the cooling system as well. Is it worth doing? Would it cause any issues being up here in PA with cold winters? Wondering if it would help with longevity too by running it cooler. Anyone have any experience/recommendations?

2013 Jeep Wrangler

When taking off from a stop, there seems to be something hanging up and I can physically feel it slowing down. It’s not constant, but let’s go and starts up again in a few feet. Traction control lights come on goes into like a limp mode. Seems to do better when starting off on a downhill. I read online it was the front wheel hubs and I replaced them but it’s still doing it. Can anyone point me towards a fix or what to check next? It’s about to drive me crazy.

Thank you in advance. I would really appreciate some help.

I just purchased a Jeep JK and want to add a 2 inch spring lift. I have read that the Jeep should be lowered from the lift before tightening the ball joints or they will resume the position they were in originally and create more of a rough ride. Any advice would be appreciated.
