hello all,

i'm interested in swapping out my t40 tranny for a t50. i have a '78 toyota corolla wagon te38. what do i need to watch out for? heard that depending on the year of the t50, shaft length and spline numbers could be different.

Umm. We don't have TE38's here but I'm guessing it'll be more or less the same. I think you'll need an earlier T50 (like out of a Celica), with the forward shifter, and smaller output shaft. Apart from that, everything should bolt on. I think.

the celicas over here didn't use t transmissions, fook

i'm assuming this guy is from the us, and i *think* it's a straight swap as long as you have the same-ish year model

celicas were 20r-22r powered

yes i am from the us folks, napa california to be exact. the car i have is a 1978 corolla station wagon and i am looking to replace the 4 speed with a 5 speed for a little more speed. eventually i am going to swap the 2tc with a modified 3tc.

Even if you get the wrong box, as long as the bellhousing is correct it's no real big hassle to change it over. You'll need a new yoke for your tailshaft (output spline different), and you'll need to cut your transmission tunnel slightly for the different shifter position, but overall it's not too difficult.

 

One thing to watch out for though, is the height of the mounts. I've used both boxes in my car, and it *appears* to me that they have different height mounts, with the later ones having a slightly shorter mount. Well, I think so anyway, because I'm almost certain originally my engine was level, and now with the later 22 spline box the engine leans over backwards.

Also, I've heard that the extension housings are interchangeable, so if you don't want to cut the transmission tunnel and change yoke etc, you may be able to just swap the extension housings across.

5th gear is only good for a 300-500 rpm drop

i have a '78 te38 i will be picking up as soon as the guy is done using it for a deer blind

check your axle code, you may just want to "up" your ratio...i did on my ke18 and am wayyyy happier
