I'm not sure. The last time I spoke to him he seemed pretty happy with the turn out. I spend most of my time on the LOST Jeep Liberty forum in which I know at least a dozen different people who have them. Most people are paying the extra money for the black powdercoat pans vs. the cheaper plain aluminum pan. Jeep Liberty owners like the PML pans because they now have a drain plug, plus the drain plug is magnetic. The pan also has a place for a temperature sending unit.

Unrelated to the oil pan but related to the AW4:

Can you tell me more about your shift kit? Is it all in the valve body?

Not all of it. Accumulators are also modified.

Re: Everything you ever wanted to know about the AW4

96 Country: does anyone know proper output voltages to C14, C15 and C16 TCU pins for an AW4? The reason I ask is that I can lock up torque converter with a manual switch sending battery voltage to new solenoids but can not get normal TCU lockup. I have changed out TPS and VSS so it looks like a problem with power supply to TCU or bad TCU.

If TCU sends less than 12 volts, will 12 volts damage solenoids?

Re: Everything you ever wanted to know about the AW4

It is cycled, TC lock/unlock, but TCU logic and a brake switch!!!!

Re: Everything you ever wanted to know about the AW4

Did you change out the VSS or the OSS? VSS is on the transfer case by the rear output housing, and has nothing to do with the TCU, the OSS is on the side of the transmission adapter housing and is usually hidden under the 4x4 linkage bracket that bolts to the side of the trans/tcase. The OSS is the one you need to worry about when it comes to trans functionality.

The solenoids run on regular auto DC power - anywhere up to around 14 volts should be fine for them. approximately 0 volts for OFF, approximately 12-14 volts for ON.

IIRC the torque converter lockup solenoid drive is based on a combination of the brake light switch, throttle position sensor, and NSS. It won't lock up (at least in my experience) in 1st or 2nd, only in 3rd and OD. So if your TCU thinks the gearshift is in 1-2 position for some reason it won't lock the torque converter at any time, same if it thinks the brakes are engaged. Let me know if you need any other info.

PS - I usually check replies to this thread within a day or two guys, and my inbox is almost always perilously close to filling up. Questions here will usually get my attention, I may or may not be able to reply to a PM until I clear out my inbox though, and I prefer to share this info as freely as possible to help more people so I'll generally post answers here.

Re: Everything you ever wanted to know about the AW4

I want to know where to get the connector for the TCM for a 2001 XJ.

The reason I ask is that I want to build a mod box that remaps the shifter so it operates as follows:
1-2 First gear only with engine braking
3 Second gear only with engine braking
D Operated by the OEM TCM but with an OD lockout switch

I looked at the Montana Fab box and it is quite nice, but it solves only half of my problem. I often drive towing a trailer and need an easier way of selecting or deselecting OD lockout than moving the whole shifter. An OD lockout switch on the steering wheel would make me happier, and my wife *much* happier.

Ideally I would like to find both the male and female connectors so I can plug the current TCM cable into my mod box and a cable from my mod box into the OEM TCM. I did send an email to Montana Fab several days ago asking whether they would sell me the connectors but haven't gotten a response yet. I am hot to trot so if I can find the connectors elsewhere I would like to get this project rolling.

I see that several years ago kastein bought several TCMs to tear apart and reverse engineer. If he or anyone else has a cheap (it doesn't have to be working) TCM and/or the plug with several inches of wires for sale I would like to buy it/them.

Re: Everything you ever wanted to know about the AW4

Sometimes you can locate plugs and pins from a dealer. Some of it they can order, some they can not. Good luck.

Re: Everything you ever wanted to know about the AW4

@ child9
We are over 60 miles from the nearest Jeep dealer and they aren't very helpful on the phone.

@ Ecomike,

Yes, I finally found an electronic parts distributor that is willing to sell me the plugs in quantities of less than 360 and has them in stock, but the socket still has me stumped. The only distributor/retailer that I can find that will sell the sockets in small quantities promises delivery in 8 weeks! Minimum quantity from anyone else is 390.

So I'm still interested in any 1997-2001 TCUs, working or not.

Perhaps you can salvage them from scrap yards.
