[TR] toyota transmission

[Bob Danielson]

Frank,
Here's the gear ratios (http://tr6.danielsonfamily.org/5speedRatio.htm)
Mine was out of an '83 Celica and has the 0.783 5th gear but I never could
find any markings on the tranny case itself. Further down that page you can
see how I determined the ratio. 

There are lots of W58 tranny's out there but only the ones listed in gear
ratio table will fit without any modifications. Having said that........Dane
Wilson is using a W58 from a '92 Supra but it required changing out the
Shift Lever Housing to the same one on the tranny's that Herman recommends.
It's Toyota part number 33502-14100 and costs about $130. Expensive part but
it opens up more W58 trannys that will work with the kit. 

Here's some good links:

hi Guys
Is there a way to tell one Toyota W transmission from another?
I of course want the W-58 with the 0.783 fifth gear.
I realize I can paint a dot on the input and output shaft, put the trans in
5th and turn the input one revolution.
But if there is a marking somewhere on the casing, its a lot easier to get
the junk yard to check it over the phone and save myself running all over
California.
Also I understand there are some differences in bellhousing to gear shift
dimension? Yes /no?
If so how is that dimension difference achieved?
thanks
