hey folks!
I'm on a weekend trip in Truckee and have a new problem on my '93 FZJ80 with the A442F automatic transmission (there's also an HDT-1 engine swap). I'm not too knowledgeable about cruisers so forgive me if my questions are a bit easy.
So I'm getting sudden downshifting when driving on the highway. It seems like it'll suddenly go down a gear, I'll watch the RPMs rev, and then it'll jump back up to the correct gear. Happening maybe once a minute or so and it's pretty jarring and can feel unsafe. The rpms aren't redlining so it seems like it's only going form 4th to 3rd, but if I turn off the O/D it seems to pop form 3rd to 2nd randomly as well. (or maybe it's always jumping the 2nd?)
I called a transmission shop, and they can't look at it soon but they suggested the problem might be as simple as a corroded transmission wiring harness. That sound like a possible culprit? I want to try their advice, disconnect the wiring, clean and check the wires a bit, and then try again.
Now my stupid question: Where in my engine compartment can I actually find the transmission wiring harness? The Toyota A442F manual just says to do this:
Unfortunately, that's not quite enough info for me.
I also know from the manual the wiring should look something like this:
But looking around my engine I wasn't able to locate this. Any tips on where in the compartment I can find that connector? Will it involve removing other parts of the engine to make it accessible? If anyone happens to have a picture of their transmission's wiring's location around, that'd be super helpful.
I'm traveling in Truckee at the moment and just hoping I fix this at least enough to make it back home to the bay area where I can really dig in on the problem.
hope everyone's rigs are holding up better than mine!
cheers
