This is my experience getting a TC lockup switch fitted with speed controlled automatic switching.
I was pretty sick of towing in 4th all the time, and the auto not locking up in 5th (or in reality unlocking at the slightest bump in the road, change in road surface, truck driving past etc.). So I decided to put in a lock up switch, and being a lazy sod, wasn't keen on having to lock and unlock it manually, or remembering to do so. So I approached Richards Auto Electrical in Murray Bridge, as they do the lockup kit for the 100 and 200 series cruisers. Seeing how the NT onwards has the Aisin box, same as the 100 series I thought it may be worthwhile.
Stefan was happy to give it a go using the Wholesale Autos lock up switch as he hadn't done anything to date with the Pajero, and wasn't sure how well his TC lockup module would work with the Pajero electronics. He was happy to mate it with his speed sensor switch controlling the locking and unlocking.
Being the first, it took the best part of a day to fit including a couple of hours troubleshooting the speed sensor wire. The kit works well, in Auto mode, it will engage at about 80 on the speedo, and disengage at 70. In manual mode it will engage at 40, disengage at 30 (it's called manual mode cause you have to select a lower gear or you get pretty severe shuddering).
I've used it for a trip to the Pilbara (13500 km) and NSW / Victoria (about 5000 km). Much more relaxed having the auto lock up, I usually drive in sports manual mode and keep an eye on the engine load via scan gauge. If the load is too high I drop back to 4th (or whatever is appropriate). Auto stays locked up, auto temps are always under 90. But if the terrain is benign I have driven it in Drive and just kept an eye on the load.
The only issue that occurred with fitting it was sorting out getting the speed signal. Originally it was taken from the sensor wire to the info display, but that meant the loss of the signal to the display, so no average fuel or speed. The info display is very sensitive to the signal quality, and having the lock up speed switch in the circuit obviously provided some interference. We tried several different diodes etc. to clean up the signal, but no go. For the first six months, I lived with no speed related stuff on the info display. I eventually got it back to Stefan (my delay, not his) and he picked up speed signal from a wheel sensor. All works well now.
I'm pretty happy with it, it makes towing easier, and helps manage fuel consumption. Don't have to worry about remembering to switch it on and off, can leave it in auto and just drive off.
Stefan has been great to deal with, no problem sorting out issues, even picking up my car for the last lot of speed signal fixes and dropping it back to me. I believe he is going to put the kit out for the Pajero, using all his stuff. Contact him if you are interested. http://richardsauto.com.au/wp/
