olskool Posted January 10, 2007 Report Share Posted January 10, 2007 Ok. I need a bit of help. I have finally got my 4age home and I have begun tinkering with it and the parts that I have. I bought a 2tg engine ages ago and a gearbox came with it. The guy I bought it off said that the 2tg had the same block as the 4age. Turns out he was very wrong. Anyway, the gearbox that came with it has a bit of work, like short shifter and a slight rebuild so I don't want to waste it. Now, the question is this. If I was to sort out a T50 gearbox bellhousing would it bolt onto the gearbox from the 2tg. Just to quickly pop it into this thread, if anyone has one please PM me. Another question is this. What gearbox do I actually have. It came straight off a 2tg. It is a 5 speed box, and another way of identifying it is the following. It has a hydraulic clutch. All of the gears including reverse are in their usual spots. Only thing is that to actually get into reverse you have to pull the gearstick up and then place it into reverse. It has a little lockout pictured below. So if anyone could help me out with this situation it would be much appreciated. http://i89.photobucket.com/albums/k209/ols...olla/cutout.jpg Quote Link to comment Share on other sites More sharing options...
irokin Posted January 10, 2007 Report Share Posted January 10, 2007 Its an early T50. It will bolt onto your 4A with a 4A-GE T50 bellhousing but don't expect it to last long. Demuire on these forums went through something like 3 boxes when he had his car setup that way. The front seal leaks if I remember correct.

flat out Posted January 10, 2007 Report Share Posted January 10, 2007 any thing rearwheel drive with an a model motor, such as ae71's and ae86's Quote Link to comment Share on other sites More sharing options...
Hiro Protagonist Posted January 11, 2007 Report Share Posted January 11, 2007 (edited) any thing rearwheel drive with an a model motor, such as ae71's and ae86's and TA22/23 Celicas (RAs had the W50 I believe), but pretty sure there are some minor differences, such as number of splines Edited January 11, 2007 by Hiro Protagonist Quote Link to comment Share on other sites More sharing options...
Des Posted January 11, 2007 Report Share Posted January 11, 2007 (edited) Celica T-50's have 20 splines and AE T-50's have 22 splines I THINK. Yep some RA's had a W50. Edited January 11, 2007 by too quick Quote Link to comment Share on other sites More sharing options...
irokin Posted January 11, 2007 Report Share Posted January 11, 2007 and TA22/23 Celicas (RAs had the W50 I believe), but pretty sure there are some minor differences, such as number of splines They DO NOT LAST behind a 4A. You'll be replacing the front seal every month or so. Quote Link to comment Share on other sites More sharing options...
styler Posted January 11, 2007 Report Share Posted January 11, 2007 (edited) theres actually a few variants of the t50, maybe someone should do a writeup :hmm: ta22 t50 t18 t50 sprinter t50 aus sprinter t50 import any more? anyone know the differences? some info comes to mind: *edit - this info below is going to be edited so i can do a writeup guide, feel free to add, correct or modify* theres a 20 and 22 spline output that distinguish the two boxes apart 20 spline = early gearbox from ta22(2t/2tg) 22 spline = late gearbox from t18 (3tc), sprinter (4ag) all t50 gearboxes split case alloy, 4 castings (bellhousing, 2 halves and shifter extension) 4 speed = t40, 5 speed = t50 t18 has a longer shifter housing but is interchangable 22 spline is stronger 1st and 2nd gear bellhousings are different ta22 / ae86 / t18 bellhousings are interchangable 4ag adm / jdm difference t18 has different bellhousing to celica as in piviot point is different i found out bellhousings and shifter housings are interchangable can't use a 22 spline for a 20 spline or visa - versa unless changing tailshaft or weld new yoke on old shaft 20 spline for 200hp driven sensibly or 150 driven harshly 22 spline for 250 hp driven sensibly or 180 driven harshly clutch friction plate the same splines and size flywheels will fit some boxes but not others due to some being larger. early box has smaller front bearing and later box has a bigger front bearing shifters and shifter housings are different with t18, ta22, 4ag output seals not the same 20 spline and 22 spline clutch setup not interchangable unless flywheel the same early gearboxes are shorter in length and later gearboxes are longer in length front seal is the same gearbox ratios short shift kits avaliable as well as replacement nylon gearstick bush early t50 input shaft smaller tip, later t50 input shaft bigger tip not sure on all of this but id like to know so help out if you can!

Des Posted January 11, 2007 Report Share Posted January 11, 2007 Power ratings on gearbox's mean nothing, I could drive around with a stock T50 on a 200hp 4age and never break it and then i can drive it around with a stock 4ac and i could break it easy as. Its all down to how you drive it, You flog it it will die you drive like grandpa and will last a long time. Shock loading kills gearbox's not so much the power unless you stick a T-50 on a 1UZ :hmm: . ADM T-50 clutch slave on passengers side. JDM T-50 clutch slave on drivers side away from hot exhaust.

olskool Posted January 12, 2007 Author Report Share Posted January 12, 2007 Wow now that is a lot of info to take in. Thanks heaps guys. Much appreciated. So basically I want to opt for the 22 spline gearbox. So if I was to go to say pick n payless or even ichiban etc. what exactly would I ask for. Would it be best just asking for a jdm box to make the search easy and the conversion less painful. If I was to ask for the jdm box would it be a straight bolt on to the engine, with no mods at all.

styler Posted January 12, 2007 Report Share Posted January 12, 2007 (edited) true... usually in 4 stroke 4 cylinder a lot of one = a fair amount of the other though, in a super oversquare single cylinder 2 stroke or a mega undersquare v8 diesel motor it may not be quite the same!

skiddz Posted January 21, 2007 Report Share Posted January 21, 2007 They DO NOT LAST behind a 4A. You'll be replacing the front seal every month or so. that is absolute bs dude they are EXACLY the same box (except output shaft) the front seal will not need replacement every month, i have compared the standard 2t and 4a bellhousings and the rear mounting surface is EXACTLY the same i know theres a 21 and 22 spline input that distinguish the two boxes apartsplit case alloy / steel case t18 has a longer shifter housing but is interchangable 22 spline is stronger sprinters need 22 spline cos 21 spline leaks and isnt as strong bellhousings are different ta22 / ae86 / t18 t18 has different bellhousing to celica as in piviot point is different i found out adm and jdm bellhousings, starter or slave swap sides or both swap bellhousings and shifter housings are interchangable can't use a 22 spline for a 21 spline or visa - versa unless changing clutch friction plate 21 spline for 200hp driven sensibly or 150 driven harshly 22 spline for 250 hp driven sensibly or 180 driven harshly well its clear you don't know at all, cos its 20 and 22 spline, and that is the OUTPUT shaft. clutch plate slines are the same i have a fuking celica t50 hanging off my 20v go figure dude? and again the 20 spline is the same strenght as a f@$kin 22 spline. those last 2 lines of your post are also bullshit, as is most of the information in this thread, in your whole post there are only 4 points that make sense and they are bellhousings are different ta22 / ae86 / t18 t18 has different bellhousing to celica as in piviot point is different i found out adm and jdm bellhousings, starter or slave swap sides or both swap bellhousings and shifter housings are interchangable /rant Quote Link to comment Share on other sites More sharing options...
