P0700 Troubles

Hi all recently got the P0700 trouble code. Took it to Advance Auto and got a p0740, solenoid stuck open. Replaced the solenoid pack and the check engine light came on again (after being cleared) with P0700. Any ideas? Thanks

How does it drive? And can you get through inspection with the check engine light on? P0740 has to do the torque converter lock up. Is it the 545 trans?

It has trouble downshifting and is burning fluid. Yes, it is the 545 trans (02 Overland 4.7 HO)

it is suggested you ALWAYS scan for codes esp with this 545RFE trans. So CEL light is on, have a scan at advance post ALL codes.

The code description you mention is a generic description, jeep defines it as P0740-TORQ CONV CLU, NO RPM DROP AT LOCKUP.

When working in trans You did replace both filters and use ATF+4, not universal or 1 type fits all just ATF+4.

Trouble downshfting- lets see what codes tell us.

You say trans is BURNING fluid - could you explain, overheating, friction?

When I see the price of OEM I think aftermarket.

There is a lot of info on the web concerning p0740 in a wj. I would read all you can find. It could be an issue with the torque converter itself, some got lucky with electrical issues in the wiring harness going to the trans. If your fluid is burnt like mine it could be the internals of the transmission are getting blocked up. Good luck

So ended up taking it to the transmission shop. Turns out that some solenoid is open and making the torque converter spin faster than it should be, hence the burning fluid and trouble downshifting. They wanted 3k for a rebuild so it looks like I'm off to the junkyard for another trans
