Newbie T4R owner here, trying to figure out what I just bought. 85 22RE auto trans.
I wanted to confirm the transmission model I have and found something interesting. According this link...
http://www.4x4wire.com/toyota/faq/parts/
...the only auto trans offered for 85 was an A340F. So, I crawled under last night with a flashlight and rag, expecting to find 'A340F' stamped on it somewhere. What I found was a tag that said...
Aisin-Warner
Model Number:
30-80LE 5000
Serial Number:
85GS-00483
So, I did some poking around the web again this morning and it appears that Aisin manufactures various parts for various makes like, Jeep, Isuzu, Honda, etc.
What I wasn't able to confirm is whether or not this IS, or basically is the same design as an A340F (just made by a different company...like an aftermarket or substitute item)? Or is it a different design entirely?
I found a few comments in various places that suggested that the Aisin was somehow preferrable (reliability) to the 'Toyota' trans. Whether it's better or not isn't so much the issue I'm trying to resolve. But the comments made it sound like maybe these were not necessarily 'stock' units, or perhaps were an option? Again...made it sound like maybe it's a different design altogther?
The trans works, but has a few issues, as does the t-case. So, I will be debating whether to try to fix what I have or do a manual swap. But first I just need to know exactly what it is I have here. One of my worries about jumping into a swap is that, if I have some odd setup now (and not knowing it), then I may end up with difficulties in the swap or an undesirable final drive ratio.
Incidentally, the PO owner mentioned that he believed this truck to be one of those early 'conversion' vehicles. I'm a little hazy as to what that exactly means (my understanding was that some of the early T4Rs were converted trucks - but that's as much as I 'know'), but perhaps this has something to do with having an odd tranny?
Any thoughts much appreciated. Thanks to responders on previous posts on similar subject. I started a new thread here for the specific topic of auto trans ID for future readers.
