Whiteline positive shift kit and perrin shifter bushing review

[Raven604]

Yes there's alot of these reviews out there but I thought I'd share my experience with these products. First of all I'd like to point out that I installed these on only 2 jack stands on the front of the car on my garage floor. I do not recommend this, it is possible but tight.

The whiteline positive shift kit was really straight forward. I used the cheater method which involved only removing 2 bolts. The 19mm transmission mount bolt and the 10mm undertray bolt. I used a Jack to inch the transmission up a bit on the exhaust hanger while I slid the bushing in. There's a lot of play you could really just push it up if you want. Bolt it back up. Done.

Driving impressions were very "positive" as this product works as advertised. It removes alot of the slop from the transmission in the lower gears and while under hard acceleration.

Thumbs up.

The perrin rear shifter bushing. Wow what a biotch. The procedures are simple enough. Unbolt the drive shaft collar and let it rest on the front pipe. Unbolt and remove the old bushing . This was simple, as all you had to do detent the bolts and hand loosen them off. It's easy if you're in neutral to get the old bushing off. Grease up the new one and slide it on. Bolt it up. Easier said the done. There's not much room to get a wrench in there to tighten the bolts up efficiently. If you removed the front pipe it would save you a lot of time since the drive shaft could drop a little lower. Even just take the drive shaft out too. On your back with 2 jack stands, It's a challenge. Anyways it got done.

Driving impressions were kinda Meh. Didn't really notice to much of an improvement. I guess when the gear engages it's a little crispier but it's still notchy as all hell.

Tomorrow the mtec shift Springs go in. Just forgot to bring home the right tools today. Motul gear 300 might go in tomorrow as well. Will post final thoughts on my transmission upgrades upon completion.

Regards to tranny oil. You may have better luck then me but Motul 300 in tranny was no better then stock. I tried many and in end Pentosin MTF2 is magic in the box.

Thanks for in the input. Should I just save the motul gear 300 for the lsd then?

Yup only know you don't use actual LS 300 just the gear 300

You can try it in tranny if like but I think you'll be dissapointed IMO.

Update: Upon driving some more clicks. I've grown to really like the perrin shifter bushing. You really start to appreciate it. It makes the shifter feel alot more solid and gives you confidence while shifting.

Thumbs up.

I put both of those bits (Perrin shift bushing and the Whiteline trans stabilizer) in today with just two jack stands...I feel your pain. Literally. I will be sore in the morning. Here are a few thoughts on each bit.

Whiteline Transmission stabilizer:

I went with the full-monty method, in part because I was curious about the bushing that is in there now and wanted to take it out completely and get a closer look. I found that I had to remove the large "shield" that covers the transmission from below to get in. Not hard, but lots of bolts. You need a 10mm, 12mm 14mm and 18mm to get all of the bolts loose for all of the bits to get that transmission mount out. The exhaust is definitely in the way. I pulled the hanger out to eke out a little more room and earn some "flex" in the exhaust--that let me fit the ratchet in where I needed it. The stock transmission mount/bushing was actually flaking off a bit even though the car is only 6 months old. I will have to keep an eye on that. Fortunately, it all went back together pretty easily, and with the stock mount completely out of the car, putting the Whiteline part in was a snap.

Perrin Shifter Bushing:

Want to start by saying this is a quality part that appears to have solid engineering behind it. As mentioned, getting the stock bushing (such as it is) OUT is not hard. Getting the bolts tightened once the Perrin is IN, is a challenge. Make sure you are liberal with the provided grease--easier to put a bit more in the hole on the bushing than it is to grease the shifter rod. My torque wrench would not fit into the shifter bushing area, so I had to go with, "it feels tight enough" using a regular ratchet and I'll check it again in a few days. Pro-tip, having a few ratchet extensions of different lengths comes in handy here. The stock bolts are 12mm and the Perrin jumps up to 14mm, so have both sockets handy. Having a bottle jack or something to hold the driveshaft up when you go to re-bolt the bracket helps, too.

Only had one good drive with both bits in the car, and it definitely feels different. You notice the transmission firmness as soon as you change gears and accelerate, and the sound coming from it is a bit different, too. A bit more of the "spinning gears" sound. The shifter is still stiff and it feels like it needs to "break in" for a bit. I missed a gear because of the change in feel when I first got in, but I got used to the more "solid" feeling of it after a few minutes. I have always been fond of this gearbox--I like it even more with a bit more crispness.

Took me most of the afternoon to do the work, mostly because of the cramped position and tight tolerances, but this little upgrade that feels worth the time and money spent to put them in. Recommended even for a novice mechanic if they have a torque wrench and some patience.

I installed these parts, and I have a question.

While when driving the car, I definitely feel it's more raw and can hear the gear whine.

But I realize when the car is off, and I tried playing with the shifter with clutch pressed, there is pretty pronounced metal click sound when going to each gear.

Is this normal? I know that stock cars will have this sound too, but it was very faint, but now it is very crisp and obvious.

I am not complaining about the sound, but was just wondering if it's normal or if something went lose

I think I had about 18" of extension on the torque wrench, super easy to get the bolts.

The click sound is normal I think, just transferred to the body more with the solid mount so louder.
