Hi from Iceland
Unfortunately, I don't have an HDJ80 landcruiser, but I do have a Patrol GQ on 46 inch tires, that has a 1HDT engine and an A442F automatic transmission that I installed myself from hdj80 1994. The electrical system is made from a landcruiser automatic transmission so I have all the features and diagnostics of a landcruiser.
I have been having problems for quite some time with the automatic transmission as it doesn't seem to want to go into overdrive. She otherwise behaves very well, shifts into third and picks up lock very clearly.
What I know:
- automatic transmission fluid OK
- electric valves are all new ( changes because lock up problems )
- over drive button works
- The A442F electronically controlled automatic transmission
I suspect two things but would like to find out if anyone has had a similar situation and has figured it out.
- The temperature sensor that allows the overdrive not to activate until after 55 degrees.
- Or Shift valve 3-4 is stuck in the valve body
I hope it's okay for me to post here.... attach one photo of the car alsoo...
Regards. Asgeir Thor
