Tundra tranny not-fun

[hobbit]

I had a little adventure today with a friend's pickup that was
shifting funny and had the check-engine light on. Here's a
little pictorial on what we found. Anyone
know if this is a common problem?

Hobbit,
Impressive diagnostics skills. Let us know how it works out. I would try to find junkyard harnesses if this is possible. I'll bet dealership retail prices will be in the $150-$200 range.

You can set up a business account with the dealership for discounts on parts for "The Hobbit Automotive Repair Emporium", tell them you will pay upon receipt (no charge account) and pay tax (no Federal I.D. number needed). This can be done in about 10 minutes at all dealerships and auto parts stores and generally saves about 10-15% immediately. You don't need business cards or letter head from your "company" and since your paying taxes there's no problem with the Feds. You won't get the deeper discounts that real busy shops get, but 15% is what it is. Mo money!

Then use a lot of dielectric grease to keep out....you know. - Dale

I finally understand why one of the Toyota TSBs for the Prius
involved a seemingly unrelated disassembly of a connector interface
on the transaxle and packing thereof with dielectric grease.
They were just trying to stave off potential internal corrosion
and tacked the mitigating procedure on top of a TSB for something
else, like an ECU reflash or whatever. I've never had that TSB
done but I'm thinking I should probably get some of said grease
into various critical connectors on my car anyways. That might
have saved this one on the Tundra, but then again the salt around
here is a powerful force...
