i currently have a tr-3550 and i dont really like how its a bit notchy and sometimes hard to down shift from 4th to 3rd. i also have a vibration when im driving about 3,000 to about 4,000rpm and its also there when not driving but just reving up and i think its the input shaft being sloppy on the pilot bearing. so with that being said, i plan to replace the flywheel and clutch and the bearings, and i didnt know what i should do with my tranny? should i rebuild it and it will be nice and smooth, go to a tko cause i can reuse my current bellhousing or go to a t56? im leaning toward the t56 cause ive read that its really smooth and the gearing is a little different. and also, ive read that the tko is very notchy and not great to shift even when new. what is your thoughts? if possible, i need good input on all the options, this is a street car that will see the track maybe 3 times a year. hopefully in the near future the car will have 400 rwhp but right now it only has 300.

I would just rebuild the 3550

yea but whats wierd is that the tranny was rebuilt about 10,000 miles ago and already feels like crap.....

just the nature of the beast, I have a tko600 and it vibrates and makes noises, its just how they are..

thats why i was thinking of going to the t56. should be much smoother and there are people selling the d and d viper kit used for around $2000-2400. i can probally get around $800 for my tranny and aluminum driveshaft and the bellhousing ect. that would make it around $1500 for me get myself a 6 speed!

Mine doesnt bother me at all, because no matter what it'll take all the abuse I put on it, after all its a mustang if I wanted nice and quiet I would buy a s197

with that being said, i should just beat the **** out of mine and wait till its actually bad and put the money into other places on my car. thanks for the advice.

the vibration your feeling my be caused by a bad harmonic balancer. they are common to commin apart.

i already replaced it and it helped a little. i also replaced the tranny mount and i think that help a tad bit also. it seems like the vibration lessens as the car and tranny heat up. but im so bias that i convinced myself that i never felt the vibration till my body guy pointed it out. i think about the situation like this" its an 85 mustang... just drive it"
