I dont like to use MM because everytime I do my transmission just smells like its burning up after you shut car off and park it and walk by it. Does anyone else have this problem . And yes I do see what your talking about with the 2nd to 3rd shift but it sucks thats normal.

I get a very bad vibration on 2-3 shifts when under "moderate" acceleration. Sometimes its worse.

I DID notice it was almost gone after I replaced my plugs and did an ECU reset, but 300 miles later it's creeping back. Not sure what effect it had. I had a mechanic in my car, he thinks its a bad 2-3 shift sensor??? Im almost out of my extended warranty. Im going to wait another 600 or so miles until it gets bad again to bring it in.... A new tranny at 95,000 will be nice

Maybe debri in the solinoids? Since these transmissions have no fuild filter.

i noticed if i get the rpms up to about 4-4.5 and shift into 3rd at about 1/4 throttle or less it wont bang..then when i do a 2 to 3rd shift it will either do it very slightly or be a real smooth shift...then once i shut the vehicle off its back to square 1 with the banging

My solution was to never use manual mode. I've actually forgotten about this issue.

2>3 hard shift is normal. Only way to fix it is to rebuild the transmission. I wouldn't worry about it.


The 2-3 harsh shift is caused by
apply timing of the high and lowreverse
clutch, not the front band.
Here’s why: The front band is holding
in first and second, but is ineffective. In
third gear, it’s part of the applied state.
The servo never loses pressure, so if
the band were slipping it would cause a
spin-up or neutral, not a flare.
The high and low-reverse clutch
applies and the forward brake releases
on the 2-3 shift. The timing between
these two shift components is critical.
The high and low-reverse clutch drum
is splined to the direct clutch and is
connected to the rear planetary. The forward
brake is located in the back of the
transmission and is splined to the case
The problem is the clearance specifications,
and there are plenty of them
out there: We found at least three and
they were all different. Having the
wrong clearance — being too loose or
too tight — will force you to remove
the transmission again. And most of the
clutch packs don’t have a conventional
selective plate.
So here’s the fix: set the high and
low-reverse clutch clearance to 0.050”
and the direct clutch to 0.060”, or as
close as humanly possible

I believe the 05/06 or maybe just 06 has the rev match like the M's which were released that same time so they added that feature so I can't imagine it being a problem in those years.....was honestly trying to hold out for a low mileage 05/06 when I picked up the 04

05 is when they introduced downshift rev-matching. 03-04 has a top gear selector.

I've had this problem from day 1, 19K miles. My car has 106K now and still shifts great. I use MM more than 50% of the time. As already stated, I'd rather it shift hard and fast.
