Just received an order from them today, they are good to go

good question, I'm interested in the answer as well. On GM vehicles we can change any engine management parameter through third party software. Not sure on these........

Thanks everyone, when mine kicks down the rpm's get to around 4,500 - 5k and it wont upshift. The engine bogs down (it feels like it hits a rev limiter). I must lift off gas and it will shift to next gear. Of course at that point I've slowed down enough that it really needs to downshift to speed...

Thanks dude for the response. I assume those of you with the 45RFE can floor it, ****** shifts down and then upshifts without lifting the accelerator?

Yeah, really odd. My dash lights dont flash and my CEL comes on periodically just driving normally (always 740 code). For everyone else, when you floor your Liberty does it shift down and then upshift while still floored or do you have to let off the accelerator before it will upshift?

If you are dragging these over rocks use G8 and simply paint with flat black because no paint, powder coat or bedliner will hold up to that. If they are on for looks and/or occasional rock kisses probably doesn't matter what grade fasteners or finish. On my dedicated rock crawler I use 2...

Dayco 89254 has 76mm grooved pulley and 90mm smooth. I believe this is the correct part number for a 2006. Is this the part you got from Advanced Auto? Gates 39120 as well. I've had good luck with both Gates and Dayco tensioners.

Typically this type of sound comes from worn brake pads, either the pad being worn to the point that there is no pad left, aka metal on metal. Also can be the warning bar which makes a scraping noise to alert the driver that the pads needs replaced. Typically its an inside pad that wears first.

Regarding the PO740 code.......the thing is I don't get TC shudder, the only time there has been any mechanical transmission symptoms is last summer when it stuck in gear as described in the 1st post. Weird. Any thoughts on the floor it/downshifts/doesn't upshift/engine doesn't rev past 4500...

Hello all, I've got an 02 Liberty 4x4, 3.7L, 45RFE ******. We bought it on 4/7/13 with 116,500 miles. It now has 129,000 miles. Under heavy acceleration (basically floored) the transmission shifts down, the engine hits 4500 RPM's and it wont upshift and accelerate unless I let my foot...

Any resolution to the 'glass' warning light? I've got the same problem and I replaced the rear glass switch today but it didn't help....also my rear wiper doesn't work, not sure if that's related or not... Thanks for the link to the service manual Billwill
