changing transmission fluid/filter

[aliciak5885]

I have an 07 liberty limited. It's at 155,000 miles. It's not shifting out of 1st. Someone recommended a transmission flush and filter change (which it hasn't had since I've owned it @ 80,000 miles). All other maintenance has been done regularly. I've heard mixed reviews on transmission flushs/changes. Some say change often, some every 100,000 miles and some say not at all because of potential transmission slips. please help and insight?

Dont do a flush.

How you checked the fluid level? Jeep running on level ground with the trans in N..

Perhaps a transmission shop can scan it and see if a solenoid is sticking? Don't flush, but a fluid and filter change won't hurt.

It has a sealed ****** from the top, no dip available to check the level.

2007 & no dipstick- what fun=Not. link: https://www.jeepkj.com/threads/2007-transmission-fluid-level.60648/
Does anyone have access to a KJ 2007 FSM and it's ATF+4 complete Mopar service description /mm & temp scale?

Measure what comes out and put that much back in.

I grabbed a dipstick from a junkyard that was entirely too long. I use it to check trans fluid on Jeeps that got the plug, just use the chart for the temps and a temp probe on the end of the dipstick.

I had a flush done on mine at about 150 miles. My former mechanic didn't get the filter on correctly, and it blew the transmission. Apparently, it isn't idiot proof.

Hi,
I decided to change the filter and fluid in my 2004 Renegade at under 180,000kms. Almost immediately the transmission wouldn’t shift up from first gear. I thought somehow I messed up. However, after shutting off the engine the transmission went back to normal. Two codes did come up, P0841 and P0731. The first one is a pressure sensor fault and the second one says Gear 1 Incorrect Ratio. This problem has happened twice more but each time it fixes itself. The problem hasn’t happened for quite awhile and the transmission has 206,000 kms on it now.
Does your Jeep shows codes?
