Topic: transmission ID?

[88toypickup]

Hi everyone.  It's been a few years since I've been an active member on a forum.  I'm not sure if this is the right spot for this post, but I'm trying to post this up before work.  I have what I think is a R150 from a mid to late 90s Tacoma.  I will post pictures as soon as I can.  Casting number on the intermediate plate (terminology?) is 61005245.  Are there any things that are dead give aways?  Input shaft length and spline count?  Out put shaft spline count?  Thanks in advance.

23 spline output shaft would indicate either a R-150 or R-151. R-151 input shaft length is 6" R-150 input shaft length is 5.5"

Don't the later tacoma r150's  have a different length input?

Oh! They might. I’m not familiar with them.

I think so,  I too have always dealt with the earlier stuff but seem to remember that.

Yes, the later R150's have a 3/4" longer input and bellhousing for the "air cooled" clutch.

The serial number isn't a whole lot of help.  The first number is the year in a decade, the second and third number is the month, the next 5 numbers are the number off the line from Aisin.  So for yours: 6- (1986 or 1996) 10- October 05245- 5245th transmission off the line from Aisin that month.  However the 5246th transmission may have been a 2wd transmission, and the 5244th transmission may have been a Jeep transmission.  There isn't like a span of numbers that were all R150's and a span that were all W56's or anything.

Post a few more comments in other active threads. Once your count is up post a few pictures. I'm sure someone can identify it for you.

Thanks for all the replies.  Looking at marlin's website it looks most like the T100 R150.  It would have a top loader transfer case.  It's a 4wd transmission, with no location for transfer case shifter.

That could also be an R150F off a tacoma or a 3.0.  The only R series that is forward shift is the R151 (the website has a 151 picture for the 150 as well). The T100 is a late style R150 (tacoma input syncrhos ect) but with a early tailhousing to go to a passenger drop tcase.
