I just recently drove an MKIV that was near stock. It shifted SOOOO smoothly compared to mines. No clunk or nothing, no resistance (compared to mines). No 2 click/stop/pause positions, (out of gear, neutral, then into the next) just right into the next gear... the way it should be no? And it had way more miles than mines. A 93, mines a 94. I'm just wondering, does my clutch have anything to do with it or is it my tranny or what? Are my engine/tranny mounts screwed? I just changed the diff and tranny fluid with some Mobil stuff (forgot exactly what). I didn't get all the old fluid out of the tranny now that i think about it cuz i didn't open the fill hole while draining it. I have the RPS CC. I can see how everyone else is running better times than me if their shifting is that easy!!! My best time is 12.4 but I'm shooting for 12.0 or 11.9's which is possible with more practice but more importantly.... a tranny working properly. I just don't want to be alone in this!!!:spank: j/k. Thanks for all input! :D

pull the mobil oil out of the tranny and either run the toyota fluid or royal purple.

that is probably your problem -- you must run the correct fluid

I don't think the transmission fluid had ever been changed. It looked pitch black and the diff was almost a cream instead of fluid. It's always been like that (not so smooth). But compared to that other MKIV, mines seemed rough. Where can I find some royal purple and is there any way to "flush" out the mobil stuff? I bought the car with 69k completely stock with no knowledge of any maintenence done to it. Some of the writing on the timing belt is starting to dissappear so i assume it's time to change that and while i'm at it, the acc belt, water pump (97's Mkiv design), power steering pump..... what else do you reccomend?

My 93 car has 25K miles. The tranny fluid was replaced with fresh V160 1300 miles ago. It shifts very notchy, not smooth. Never has been smooth for me for the whole 1300 miles I've had it. I was figuring this was normal. Now I wonder why it's so notchy:(!

I'm pretty sure the clunk is normal though. If you do a search on here for "getrag" and "clunk or thud" you'll find LOTS of people saying that the clunk is normal. I wonder why that other car didn't clunk?

So in general, do most people on here have notchy shifts or smooth shifts?

I have notchy shifts and a huge THUNK like the tranny is going to fall out when I shift fast. Its like the whole car jolts when I shift it fast. I am pretty sure it must be the tranny mounts...can anyone clue in?

Would the type of clutch that you have matter at all? Supposedly this MKiv that i drove had a TRD twin disk but it felt to me like stock.

All I'm saying is that it felt as though it took a lot less effort to get it into a different gear. I couldn't hear that clunk so much in that near stock one but yes i know about the cluck. I'm trying to get used to that clunk but after the RPS CC install, when i shift fast and release it seems as though the whole car will just jerk when the clutch is engaged. And it slows me down... alot, enough so that when i was racing a Z06, everytime i tried to shift fast, he would move up a feet or two... other wise we were side by side. And it's not cuz i shift that slow either.

I want to think it's the tranny mounts also! I would imagine the jolt is caused from the position of the tranny vs drive shaft. I'm sure it would be better if they both stayed in one place but if one moves (tranny) it would create some kind of jolting.

I had problems going from 1st to 2nd...3rd to 4th....5th to 6th, but not 1st to 3rd....3rd to 6th. The shift rod was slightly bent. Its being fixed/replaced now. (the shift rod)

I can't tell u yet coz RHD is PITA am not used to shift with my left hand :( waiting for the parts to come and start converting

Hopefully by end of next month I might be able to judge with a new clutch + flywheel and fresh V160 oil.

I remember when I had my previous car(3000GT TT) shifting was very very smooth cause I was changin the gear oil every 22k miles, this car was also new it did'nt fall into other peoples hand.

I just hope nothing's wrong with my Supra's Getrag 6-Spd :p

Thanks, that's helpful for the noise :). But what about smoothness of the shift. Is yours notchy or smooth? All the replies so far are for notchy shifters, not smooth. Surely a few other people out there actually drive their cars :p .

Tranny Problems

Please understand that I am not a tech, but believe that many of the problems related to these posts are blocking rings. Yes, the fluid does make a difference, and the Toyota fluid is the best, although very costly. I experienced some problems while running the Royal Purple.

The blocking rings assist with the guidance into gear, and is often the problem if your tranny goes "glunk' when you put it into gear. For any of you that have not already installed a B&M shifter, this is something that I recommend. Although my 6-speed is not perfect, it is much better with the shifter than without.

just my 2c - i've been driving a 5 speed NA for a while, it had a very smooth transmission. when clutch started slipping. i changed to new standard clutch which initially had very jerky changes as the clutch was not "bedded" yet [i'm not sure of proper term]. after a few hunderd kms, it became smooth like before.

now driving a TT with "button clutch" [again not sure of proper term] and it is notchy as hell, off the line i'm wheel spining unless i'm super careful with clutch/gas. i'm told by the previous owner that the button clutch was necessary to hold the power [+ abuse!] without slipping/prematurely wearing out.

so maybe your notchy 6 speed is not to do with gear box but might be due to a sports type aftermarket clutch??

having spent my 2c heres a question, is there anyone who is using a "button" type clutch (ie on-off type clutch which is not easily slippable) who can give me some tips on how to start off the line smoothly without slipping tyres? [and yes i am already practicing, but any pointers would help]

My car is all stock except the suspension so that's not the reason for me.

It's the same way with mines. My clutch only clunks when depressed in the lower gears also so i guess it's normal???:scratch:
