T5 swap questions

as of last weekend i have the clutch pedal assembly installed and have picked up a new clutch plate and resurfaced my flywheel. Now I have some questions for the others who have completed this swap.

1. Is there a return spring for the clutch pedal? (hydralic clutch)

2. Will I have to remove the Y-pipe?

3. Can I use the same starter?

4. What kind of tranny fluid should I use?

5. How hard is it and what did you use to cut the floor and the holes in the firewall?

thank you Paul

No return spring. Don't have to move the Y pipe. I use a 1 1/2' hole saw to cut the hole for the master. Gonna have to pull the column. Don't have to pull the brake master as the tech article says. At least I didn't have to. Use regular ATF tranny fluid. I used an air chisel to cut the hole in the floor for the shifter. Cut it like butter. A die grinder will take forever. Not too hard. I rebuilt my tranny, just got it running today and the biotch grinds in 2nd gear. Now I have to take it back out. Oh well.

There is no reason to pull the column. All it takes is a little creative use of the ratchet. All I did was take out the 2(?) upper column mount bolts and let it drop 2" or so and it worked just fine.

As far as using ATf: I used it after I put mine in but noticed that it would grind the 2-3 and sometimes the 3-4. I switched to regular gear lube and the grinding stopped. Only problem is that on a cold morning it is nearly impossible to shift until the tranny warms up.

Just my $0.02

Good idea. Wish I would have thought of that. Oh well. Next time. And I'm sure there will be one.

1. Is there a return spring for the clutch pedal? (hydralic clutch) No. I highly recommend using a new clutch master/slave cylinder unit though. Don't cut the straps holding the slave cylinder in until it has been installed.

2. Will I have to remove the Y-pipe? No

3. Can I use the same starter? No. The auto starter is too large in diameter.The T5 uses a different starter and mounting bolts.

4. What kind of tranny fluid should I use? ATF for WC-T5, Gear oil for non-WC T5.

5. How hard is it and what did you use to cut the floor and the holes in the firewall?

Not hard. I used a Dremel to cut both. A die grinder and hole saw would be faster. Pulling the brake booster out or disconnecting the steering column makes it easier. I chose to remove the brake booster. Use the lower shift boot as a template. There is a punch-out in the insulation that lets you know where to make the clutch master cylinder mounts.

Also don't forget to reroute the ground wire for the hatch release (black with white stripe) from the auto shift lever assy to the ground of the parking brake. If you don't you'll have to press on the clutch to release the hatch. The large gage purple wire is rerouted to the Neutral Safety Switch on the clutch pedal. If you have a cruise control there is another wire to splice over to the clutch that disconnects the cc when you press the clutch. I suggest the roller bearing style of input shaft bearing over the solid bronze one.

Your welcome and good luck, Lon.

As I replied earlier. The stock GM starter for an automatic equipped car is too large in diameter. One of the little surprises I discovered during my swap. the nose of the starter won't fit through the hole in the dust shield, that's your first clue that something is amiss. I ran down to Kragen and got a lifetime rebuilt starter, came back home to install it. Only to discover that the bolts for the automatic equipped starter are about 1/2" too long. They have roll formed threads, so it's not possible to just re-thread them. You COULD use a bunch of washers to take up the gap though. An aftermarket mini-starter will work with either auto or T5 application. But is more expensive. FYI, there is also a brace at the rear of the starter. It is also different, since the GM starter for a T5 is also shorter. I got my brace from a Pick-a-Part. Many people just leave that brace off. I probably don't have to mention it, but I will. Be sure to shim the new starter per the instructions. Good luck, Lon.

I just finished doing a auto to T-5 swap last weekend, it was a snap.There is no spring used with the hyd. clutch set up. I diddnt have to change the starter.I had no problems mounting the starter after the bell housing and dust shield were on.There may be slight differences in starters from year to year though, im not sure about that. Everything went together pretty easily.I used tin snips to cut the hole for the shifter, the snips make a nice clean cut.You can use the 2 support bars from the pedal assembly as a template for your slave cylinder holes.The hardest part about the swap is getting your speedo right.You need to know which speed sensor to use for the year car you have and rpo code for that sensor if you dont have a part number, and you need to get the correct speedo gears for your final drive ratio.

I've been told that early cars already have the smaller diameter starter. Mine is a 90 and had to be swapped.
