06 Wrangler unlimited shifts hard from 1st to 2nd

I have an 06 wrangler unlimited it had 69000 miles on it about 3 days ago it started to shift HARD from 1 to 2. It stops after I have driven it for a few minutes. I had my transmission gasket done two years (36848) ago and they changed the fluid but not the filter. Any clue what it may be??

Hmm . . . typical 42RLE behavior maybe? Have you checked the fluid level and color recently?

I am assuming that you have the 6-speed manual???

I also have a 2006 Unlimited, but only have 35k miles on it. I have always felt that first to second was a rough shift. It has just never felt like it wanted to go in to gear. I had a dealership look at it within the first few months that I had it (I bought it new) and they said it was shifting normal. Since then I have read a lot of reports of others having the same problem. It seems that it is just this transmission, which is also in the 2005 model. Luckily I have the Rubicon so I just start in second most of the time.

If yours suddenly got worse, there may be a problem. How many miles do you have since the last fluid change?

6-spd wouldn't have a filter. He's probably referring to the notorious 42RLE.

Please help us by filling out your profile. And: why would you change the fluid on an auto without changing the filter???? You would only saved a few bucks in exchange for many headaches.

Anyways, automatic transmission fluid is a strong detergent, and autos do not like small foreign particles floating around because they can clog fluid passages. Maybe the new fluid kicked around some of the foreign particles from the old filter, making the shifts harder?? Just a thought. Otherwise it could be the bands are bad, servos, pumps, yada yada yada

Interesting... I have the same model and transmission and bought the Jeep used with about 55,000 miles on it. It's shifted like that since I bought it. It got better for awhile after I replaced the speedo gear with one that matched the tires, but then regressed after a few weeks. Also got better for awhile after I re-geared. Now it's a mixed bag. Sometimes a hard shift, sometimes not. Seems to not like it if I am not accelerating moderately during the shift. I'm just living with it, but would be interested to know if it indicates a problem.

I went through this about a month ago after cleaning the IAC and throttle body. It would rev up pretty good in 1st, then shift really harsh into 2nd. You could really feel it even to the point it lunged so bad I wouldn't drive it for fear of tearing up the transmission or U-joints or something.

I took it to a good transmission shop in my area to check it out and all they wound up having to do was hook up to the computer and do some re-programming. It's shifted great ever since and they didn't even charge me for it! Have no clue if yours could be something like this but I just thought I'd throw it out there. Good luck!

Could of been refering to the IAC? I am not sure.

First thing/easiest thing to do is check fluid levels, engine at normal operating temp, go thru the entire gear range (allowing a few seconds pause in each gear) end back up at park and check the fluid. It can't be too low OR too high.

If it's low, then there you go.

Next, I would change the fluid and filter anyways, 30K on fluid and X?? on filter sounds like it is about time. If that solves it then yay.

If your still stuck in a rut after that, its off to a good trans shop

(at least, this is what I would do)

Mine has been doing the exact same thing right after I drive it for the first time after sitting a little while. I have disconnected the battery and this seems to cure it for the time being.Well see.Second time I have had this happen.Does anyone know where on the transmission the sensor actually is or where to get a new one?
