Re: How-To: Speed3 Trans Swap Into MZ3

Install Procedure

This procedure is for an '05 MTX. This is how I chose to do it, there are different ways, but having pulled the trans before, this is what I think is the fastest and easiest to do, WITHOUT A LIFT.

1) Raise front of car on jack stands as high as you can

2) Remove the front wheels

3) Use an impact to remove the axle nut/bolt (NOTE: if you do not have an impact, have someone hold the brakes while you loosen the nut/bolt)

4) Remove the brake caliper and caliper bracket

5) Remove the bolt which holds the lower ball joint in place

6) Remove the 3 bolts which holds the lower control arms on (NOTE: You will need a very long breaker bar for this)

7) Remove the LCAs and set it aside

8) Remove the 3 bolts which mount the strut hat to the tower

9) Remove the entire strut assembly from the car

10) Remove the bolt which holds the steering knuckle to the strut

11) Using a maul hammer, hammer on the steering knuckle to separate it from the strut

12) Using a maul hammer, hammer the new steering knuckle onto the strut (NOTE: be sure you have the correct side knuckle)

13) Insert and tighten the bolt that holds the steering knuckle to the strut

14) Set the struts aside

15) Remove all plastic covers in engine compartment

16) Disconnect the battery

17) Remove the battery

18) Disconnect the ECU

19) Remove the 3 bolts which hold the battery tray in place

20) Remove the battery tray and set it aside

21) Remove your intake

22) Remove the 4 bolts which hold the header heat shield in place

23) Slide the header heat shield back towards the firewall (NOTE: you do not need to full remove this, just slide it back for clearance)

24) remove the 4 nuts which hold the drivers side mount bracket in place

25) Remove the 2 nuts which hold the battery box bracket in place

26) Remove the battery box bracket and set it aside

27) Drain the transmission of oil

28) Remove the 3 bolts which hold the passenger side jack shaft in place

29) Remove the passenger side axle assembly (NOTE: I left the drivers side axle in until the trans was out. it is hard to get out due to the snap ring)

30) Remove the 3 bolts which attach the rear motor mount bracket

31) Remove the rear motor mount

32) Place a floor jack with a block of wood under the engine

33) Pump the jack until the wood contacts the oil pan, then give it 1-2 more pumps until it is supporting the engines weight (NOTE: do not lift the engine too much)

34) Loosen the bolts around the perimeter of the transmission bell housing (NOTE: do not remove the bolts all the way yet)

35) Place a transmission jack under the transmission and pump it until it is supporting the transmission

36) Remove the bolt which attaches the transmission to the drivers side mount (NOTE: you are going to need that breaker bar again)

37) Remove the drivers side mount

38) Remove the shifter cables from the transmission

39) Unplug the 3 connectors on the transmission

40) Remove the 2 bolts that hold the slave cylinder on

41) Remove all the bolts around the perimeter of the transmission bell housing

42) Separate the transmission from the engine

43) Lower the transmission out of the engine bay and then slide it from under the car

44) Remove the 6 bolts that hold the pressure plate on (NOTE: you will need an impact for this)

45) Remove the clutch and pressure plate

46) Remove the 6 bolts that hold the flywheel on (NOTE: you will need an impact for this)

47) Rock the flywheel back and forth to remove it

48) Remove the 6 bolts that hold the rear main seal on

49) Carefully pry off the rear main seal

50) Put a bead of RTV along the where the block meets the pan and install the new rear main seal (NOTE: read the directions on rear main seal)

51) Use a seal puller to remove the pilot bearing (NOTE: This is difficult to do as it does not want to come out, be very careful when doing this as you will mangle it)

52) Insert the new pilot bearing and use a socket to tap it in place

53) Remove the release bearing from the MS3 transmission

54) Install the new release bearing on the MS3 transmission

55) Install the MS3 flywheel

56) Insert and tighten the 6 flywheel bolts to spec

57) Place the pressure plate and clutch against the flywheel and insert the alignment tool

58) Insert and tighten the 6 pressure plate bolts

59) Remove the alignment tool

60) Remove the interior kick panels around the tunnel

61) Remove the 2 nuts that hold the shifter linkage to the firewall

62) Remove the 4 bolts that hold the shifter base to the floor

63) Remove the shifter base

64) Slide the shifter linkage into the interior of the car and remove it

65) Slide the new shifter linkage through the hole in the firewall and into the engine bay

66) Install and tighten the 2 nuts that hold the linkage to the firewall

67) Install the 4 bolts that hold the shifter base to the floor

68) Apply some anti-seize to the end of the MS3 transmission input shaft (NOTE: this is to make it easier to slide into the clutch disc)

69) Place the transmission on the trans jack and slide it under the car

70) Lower the engine slightly so it is at a bit of an angle

71) Jack the transmission into place (NOTE: you will need to make sure the trans is in the correct orientation in order to get it to fit in)

72) Slide the input shaft into the clutch and make sure everything is lined up

73) Push the transmission into the engine

74) Insert the bolts that attach the transmission bell hosuing to the engine and finger tighten them

75) Gradually tighten the bolts until the gap between the engine and transmission closes

76) Jack the engine and transmission up until they are level again

77) Tighten down all the bell housing bolts to spec

78) Place the drivers side mount in place

79) Jack the transmission up until it is flush witht he mount

80) Insert and tighten the drivers side mount bolt

81) Lower the transmission jack and remove the jack from under the engine

82) Remove the axle seals with a seal puller

83) Install the new axle seals by gently hammering them in with a socket

84) Install the Axles and fill the transmission with oil

85) Insert and tighten the 3 jack shaft mounting bolts

86) Install and tighten the rear motor mount

87) Insert and tighten the 3 rear motor mount bracket bolts

88) Insert and tighten the 2 bolts that hold the shifter linkage bracket to the transmission

Re: How-To: Speed3 Trans Swap Into MZ3

Thats a lot of work!

Wondering if its worth it?

 

Re: How-To: Speed3 Trans Swap Into MZ3

Dang, I'm SOL.

 

Re: How-To: Speed3 Trans Swap Into MZ3

Added pics of all the parts today. tomorrow i will be doing the swap. i will do my best to take pictures of the process. i will also be sure to get pics of all my stock parts once they are all off.

Re: How-To: Speed3 Trans Swap Into MZ3

the trans is in. i am waiting on another axle seal as i demolished one trying to wedge the trans in. that thing barely fits. literally a hair between the differential and the LCA mount. almost need to drop the front sub-frame to get this beast in, tho i did it without.

 

Re: How-To: Speed3 Trans Swap Into MZ3

Awesome. Good work! Have pics?

 

Re: How-To: Speed3 Trans Swap Into MZ3

pics will be up soon. didn't get a chance to take good pics as we were too bush trying to get it to fit. it took us probably 30 mins to just get the transmission to fit in the enginebay. multiple times of jacking it up with the trans jack, trying to move it, lowering it, repositioning, trying again, etc... it weighs like twice that the old one does so it is very difficult to maneuver it.

 

Re: How-To: Speed3 Trans Swap Into MZ3

damn and you are doing this with a hatch which has about 2inches more engine bay clearance than the sedan.

just glad cain did this already with a sedan. goodluck. cant wait to see pictures of the finished project.
its nice to see a thread with pictures..


STICKY!

 

Re: How-To: Speed3 Trans Swap Into MZ3

Did you get the weight difference between the 2?

 

Re: How-To: Speed3 Trans Swap Into MZ3

sadly i couldn't get an exact weight. i don't have anything to weigh it.

i can tho give you an idea of the difference.

with the 5 speed i can lift it with 1 hand. it's that small and light.

for the 6 speed i could barely lift it with both arms. in order to pick that thing up i had to straddle it and lift with my legs, i can barely budge it with my arms.

overall i'd have to say that the 6 speed weighs probably twice as much as the 5 speed.

Good work so far. May start collecting parts later this year.

Re: How-To: Speed3 Trans Swap Into MZ3

Easy Question.

Did you replace the seals and the rear motor mount because of fitment issues or just because you wanted new ones? I ask this because you have these items listed on the pics of needed items, but they aren't listed in the OP.

Thanks.

 

Re: How-To: Speed3 Trans Swap Into MZ3

the seals i replaced because it would be stupid not to replace them. i didn't want to deal with leaks.

for the rear mount bracket, that is needed if your trans didn't come with one. the 5 speed bracket is different.

 

Re: How-To: Speed3 Trans Swap Into MZ3

subbed.

 

Re: How-To: Speed3 Trans Swap Into MZ3

added procedures. videos of transmissions in action coming soon.

 

Re: How-To: Speed3 Trans Swap Into MZ3

update to OP regarding slave cylinder setup.

it turns out while the slaves are indeed compatible, there are differences. the ms3 slave cylinder has a larger piston diameter. this changes the pedal effort by a lot.

with the MZ3 slave my pedal was uber stiff. with the MS3 slave my pedal is now like stock. (i have the ACT pressure plate which is 48% over stock)

if you use the MZ3 clutch line and the MS3 slave cylinder you will need to transfer the seal on the line from the MZ3 slave to the MS3 slave.

 

Re: How-To: Speed3 Trans Swap Into MZ3

Hey Verto,

I am a little confused on step 12.

The new steering knuckle?

 

Re: How-To: Speed3 Trans Swap Into MZ3

yes. i chose to replace the knuckle for my application. it is easier to swap the knuckle than to press the hubs out. hubs needed to be changed for 04-05

 

Re: How-To: Speed3 Trans Swap Into MZ3

Got to say that this is one awesome writeup. Hats off to you Verto.

Should have all parts next week, so the fun will begin then for me.

 

Re: How-To: Speed3 Trans Swap Into MZ3

About the speedometer. . .

I have a MZ3 ATX but I also have ABS brakes (with wheel sensors obviously).

So can anyone tell me if if I would get a speedo reading if I swapped?

I am thinking about just dropping an MS3 engine/trans combo in. If I put a new computer thing in I think that should take care of all these potential issue. . . . plus I get a turbo too yay
