Mister_Chi Posted October 23, 2005 Report Posted October 23, 2005 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.

demuire Posted October 25, 2005 Report Posted October 25, 2005 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. Quote
mikeys toy[RL] Posted October 25, 2005 Report Posted October 25, 2005 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 Quote
Mister_Chi Posted October 25, 2005 Author Report Posted October 25, 2005 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.

demuire Posted October 25, 2005 Report Posted October 25, 2005 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. Quote
demuire Posted October 25, 2005 Report Posted October 25, 2005 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. Quote
mikeys toy[RL] Posted October 25, 2005 Report Posted October 25, 2005 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 Quote
