I just reread this.  Shotpeening isn't a wear and tear preventative, it's a strengthening procedure.  Makes metal more resistance to shock  loads.

When the white plastic bushing at the base of the shift lever falls off it makes the shifter very loose & sloppy. Putting the car in reverse becomes difficult. It feels like it almost does not want to engage even though the shift lever is pushed all the way back in reverse. Some times it will even grind. It is easy to fix the shift lever bushing problem. You place a 3/8" washer 20mm wide by 2mm thick with a 10mm hole in it at the bottom of the hole that the shift lever goes in so the bushing on the end of the shift lever can not fall off any more. Now that I have placed a washer into the hole below the shift lever bushing so the bushing does not fall off anymore shifting is very precise. Now it slips into reverse very easy every time & there is less play in all the gears  :lock:
.
.
.
(First) go to Home depot & get a 3/8" washer it should be 20mm wide with a 10mm hole in it 2mm thick.
.
.
.
.
.
.
(third) remove the four bolts from the shift lever rubber boot & the three bolts from the small rubber boot underneath it as seen in these pictures
.
.
(fourth) remove the shift lever from the transmission as seen in these pictures
.
.
.
.
(fifth) place the 3/8" washer that is 20mm wide x 2mm thick with a 10mm hole in it into this hole
.
.
.
this will stop the white plastic bushing at the base of the shift lever from falling off down into the hole here is a five page thread for more information if you need it. > http://www.mazda-speed.com/forum2/index.php/topic,321.0.html

that is exactly what happens when the bushing falls off & what putting the washer under it fixes. I have a feeling there are a lot of mazdaspeeds out there with bushings that fell off.

So at 35k I had my car in the dealership for warranty work.  I had grinding in 3rd and 4th.  Seems the 4 bolts on the shift plate came loose, which is common, and the gears were not being positively engaged.  3rd and 4th were pretty chewed up and some other small stuff was bad.  Well the dealership rebuilt the trans and I got the car back.  3rd was really hard to get into and 4th could be stubborn as well after the rebuild.  Here I am 900miles after the rebuild and 3rd and 4th took a crap again.  I think a guide pin broke for the third and Im not sure what the hell happened to 4th.  I know one other member had the same problem and an acquaintance of  mine had a 04 and had it in three times within the first 3000 miles for the tranny.  So are these trannys worth a crap or what?
I had a similar thing happen to my transmission. First my shift lever was loose & sloppy & difficult to engage into reverse. second my synchronizers went bad around 40K so I had them replaced under warranty. third my synchronizers went bad again around 48K so I had the transmission replaced under warranty. I'm taking a guess maybe these problems have something to do with the 4 bolts on the shift plate coming loose or with the bushing falling off the base of the shift lever or a combination of both.

When you feel it? Does it get clunky or something?

Those are the stock cloth seats.


I changed my tranny fluid at 30k with Redline MT90 and noticed a huge improvement with shifting, so much smoother.  Since the change I haven't had a single issue getting it into reverse either, it goes right in every time, no more shifting to 1st or 2nd or moving forward a few inches.  I didn't believe the hype before, but figured I was about due...wish I had done it 25k miles ago.  Best $22 I've spent on the car.

Hmmm...  I have had shifting issues, mainly 3rd & 5th gears since I changed my tranny fluid for the first time at 50k miles.  I used Mobil 1 75w90, but I think it is more for gear lube than tranny - that may be why I'm getting the poor response.  I've ordered Redline 75w90NS and going to try that, much of the research I did says that's a good choice.  Anyone else tried that?  Hope I don't have the tranny going bad, but based on just changing the fluid, I'm assuming it's that.  I always have had a bit of trouble getting into third gear when trying to shift fast, maybe just me - hmmmm.

That isn't a tranny fluid either, it's a rear end lube.  Your better off with the MTL or the MT-90
