SR’s are the same KA tranny with a different bellhousing… I’m not sure about gearing, the casing is the same… Didn’t you take a look at the old KA tranny before you swapped in the SR? Or did you get someone else to swap it for you? ---

I’ve had both apart side by side. KA trannies arem uch weaker than their SR counterpart, but they fit it all into the same size casing. The SR has much thicker gears, and especially the shifter arms. Also, the SR tranny uses a real arm for the reverse gear, not a silly shift linkage. ---
