Adding TSX 6th gear to A3 tranny

[AKEP]

yes.

if you're gonna replace the diff with an LSD i recommend getting new bolts for it. they have a very fine thread. get a new speedo gear. it's easier to install a new one than to try and take it off your old diff. it cracks very easily. this way you have a spare if you deicde to try and take the original off of your open diff. also, syncro springs would be a good idea. i had about 110k on my tranny when i split it open. after i installed the tsx 6th and lsd, i had issues with the car popping out of 5th and 6th on the highway. the syncro's were fine it's the springs that needed to be replaced. i ended up dropping the tranny again and tearing it apart again just to replace the spring...

has the tranny been opened up before? there are a few other things i would recommended replacing if the tranny has been opened up prior to this install.

never opened. 105k on it.
besides the fine threading, is there any other reason to replace the bolts? i'll probably do it because the bolts can be had at honda for about $20
i'll look into a new speedo gear, i'll wait till i crack mine first tho =]
what are these springs you speak of?
what else would you recommend i change/look at?

Im open to suggestions, as anything you bring up could be used as guidance to anyone else that wants to do this. in ~8 years of wrenching, i've never opened a MT up, so it'll help me out too.

BTW im not doing this out of MY garage, im bringing it to 1 of 2 real garages that i have access to.

my friend who rebuilds tranny's recommended that i replaced those bolts.

well, just be careful with the speedo gear. when you're pressing it on with the hydraulic press, it has to be pressed on with 100% even pressure. they crack very easily. i opted to have a spare one because i had to minimize chances of making my downtime longer

the syncro springs are the rings around each syncro. iirc it actually keeps the car in gear once you shift into it. problem is i don't think honda sells them separately. i sourced them from a friend's shop



be very careful when you replace 6/7/9/10 in the pic above. if you over torque them just slightly the end of the bolt will mushroom and not function properly.

also, i don't remember it being in the DIY but when i dropped the tranny the second time i removed 5/8. its part of the 5 speed lockout. prior to me removing this i had problems getting into 6th gear from 5th.

if i think of anything else, i'll post up

wait... did you end up just buying what madlorglk listed, minus the blocking ring? how did all that work out for you?

i did this well over two years ago, not using the first part that madlorglk listed without any troubles i believe i mentioned that there is a thread on the elementownersclub forum that was very useful in putting this all together already, along with a pictorial how to on k20a.org

Could one just change the 5th gear out for the tsx 6th gear therefore not needing any additional parts except for the input and output gears themselves? I am happy with the gear ratios of the first 4 gears on my ep3 but would enjoy better highway mileage.
