So... why do you want to swap?
1) the 01m automatic transmission is junk... and at $4500 used, it's expensive junk
2) the 02j 5 speed is not junk, and at $600-$1000 used, you can save a lot of money converting.
3) The automatic TDI only gets about 35 MPG real world, where the manual is capable of delivering a prius challenging 50 MPG.
4) It's the "green" thing to do...
5) Your automatic transmission just died... and you want to save some money, and get better economy to boot.
This is my first instructable, Thanks to everyone who voted for me in the Epilog Challenge! I don't think I'm going to win, but hey it's not a bad try!
Who is this for?
This instructable is for owners of any Mk4 VW Golf/Jetta/Beetle... a.k.a. 1998-2006 beetle, 1999.5-2005 jetta, and 1999.5-2005 Golf. This one is specifically from a 2001 Beetle TDI ith occasional shots from a 2003 Jetta TDI. It's for the budget conscious, or for the green, or for those who want a little more power.
The automatic has a different:
Power steering line
Transmission Computer (the manual doesn't have any wires, other than the speed sensor and the reverse switch)
Shift Linkage (Duh!)
Clutch Pedal... not there (Duh!)
Wiring Harness (Duh!)
Park Neutral Relay
Since there are all of these differences, we're not going to use the transmission, transmission computer, axles, Starter, chunks of the wiring harness, park neutral relay, and probably a bunch of other stuff that was left out just because we're a bit lazy, or didn't take that photo... We're going to adapt the existing harness for clutch cancel, cruise, and reverse switch later on... we're also going to adapt one of the brackets from the automatic wiring harness to support the power steering line.
What we need
"53" relay (horn relay)
Red 3M crimp butt connectors
Reverse switch (should come with the transmission)
Clutch Switches (there are two on the clutch pedal, make sure you get the two brackets)
Shift Linkage, complete with shift boot and shift knob, there are two boot types, so it might take two tries before you've got it right
Transmission from a TDI (if yours is a 2.0 or 1.8T, try to get one from a TDI, it's got better gear ratios)
Manual Transmission Starter (the automatic one won't work)
Manual Transmission Axles
Dust Tins from the Engine (it's between the transmission and engine, and comes with two pieces)
All of the nuts and bolts that were removed from the junkyard
New Stuff Needed:
1x New Clutch (might as well throw in a G60/VR6 from www.dieselgeek.com or www.boraparts.com )
1x Dieselgeek.com sigma5 short shifter (the OEM shifter won't clear the power steering line).
2x Nuts for the wheel end of the Axles, these are one time use only!
12x Bolts for the manual transmission end of the axles, these are also one time use only
1x bottle of blue threadlocker
2x Vertical bolts for the transmission mount (again, stretch bolts!)
2L VW Gear Lube for the 02j transmission
Yes, you will need a LOT of tools for this job
VAG-COM from www.ross-tech.com
M8, M10, M12 Triple Square bits
Clutch Alignment Tool (might come in the clutch kit)
Transmission Jack (will make it MUCH easier than bench pressing the puppy in and out!)
Continuity meter (normal VOM will work)
30mm 12 point socket
Good Luck, and try to keep up!
Step 1: Prepare for the swap! Remove (almost) EVERYTHING!
First things first, don't try this unless you've got a flat area, jack stands, wheel chocks, and some help!
Loosen the front lug nuts (they're acutally bolts, so remember DON'T REMOVE THE BOLTS!!!)
Jack the car up, support it, and chock the wheels
remove both front tires
Have someone step on the brakes while you complete the following:
Remove the 30mm 12 point nuts holding on the axles to the wheel hubs.
Remove the M10 or M12 bolts holding the axles to the transmission
Start removing the axles:
Remove the 16mm bolt from the front of the A arm to the sway bar, and move it out of the way
Use a Three arm puller (or axle shaft removal tool) to push the axle out of the hub, then turn the wheel one way or the other to remove both axles.
Remove the transmission:
Go under the car, on the back of the automatic transmission dust tin is a plastic cover, remove the cover
Rotate the engine to remove the three 15mm nuts from the torque converter
Remove the battery, tray, and air box
Remove all wiring harnesses from the automatic transmission
Remove the Power Steering line from the automatic transmission mount
Remove the shift linkage using a pry bar
Unplug the Transmission cooler hoses and use a 5/8" coolant hose coupler.
Remove the Starter
Remove both upper bolts from the top of the transmission
Support the engine with an engine support
Remove the two Transmission mount bolts (18mm bolts)
Remove the lower transmission mount, this can be a pain, but it will help facilitate the removal of the transmission greatly.
Rotate the engine and transmission slightly forward using a screwjack between the engine and the subframe (the car comes with one in the trunk.. A.K.A "The Widowmaker Jack")
Place transmission Jack under transmission
Remove the four lower transmission bolts
Remove transmission (yeah, I make it sound easy!)
Prep the block!
Remove the flexplate and the dust tins on the engine... an impact would be nice here, or have someone counterhold the engine on the other side... this should be a 17 or 18mm 12 point socket.
Remove the Shift linkage:
Remove three bolts holding the downpipe to the turbo
Remove two 13mm bolts holding it to a cross member
Loosen two 17mm nuts holding a pipe clamp in place.
Slide pipe clamp to the rear of the car (sometimes this requires a hammer)
Remove the downpipe from the car
Remove the Front Heat Sheild from the bottom of the car to expose the Shifter assembly.
Remove the two bolts from the shifter assembly
Go back into the inside of the car
Remove the console, see your manual it's a bit complicated... We've got most of it in photos below... but your mileage may vary!
Remove ash tray
Remove cigarette lighter assembly
Remove Metal cross brace
Remove the Shifter handle by putting the car into neutral, then pull the thumb lever out, then yank the whole thing off HARD.
Remove the metal cover
Remove the plastic PRND321 cover by snapping it off
Remove the shifter trim slider by snapping it off
Remove the two wiring harnesses
Remove the Shift Lock Solenoid wire
Remove the two 13mm nuts, and the shifter should drop out
Now for the rest of the removal story...
