I'm not sure, it was all under warranty. If it was under my dime, an l67 would have been thrown in with a new 4t80 lol. The first trans performed OK, but threw itself into neutral on the 20-35 mph downshift. Second transmission had parkinsons whenever you were touching the gas pedal, and the tc locked VERY early. So early, you could be at 1000 rpms while cruising down the road at like 40 mph lol. It was wierd... and they found pieces of steel in the line that the TC was making. This one, I do not like. They replaced trans and tc, again. This one still has a moderate shudder going up hills when the tc is locked. And I'm determined it'* the TC, because I've replaced/tested everything else it possibly could be, and doesn't really do it if u tap brake to unlock tc.

I'm looking for my RPO label on photobucket as we speak lol. I don't feel like going out in the 25* windy weather to go get another shot.

Anyway.. back to the subject. The same transmission shop that rebuilt my grand marquis tranny, put this one in, and the one previous. Oh yeah, did I mention I had to take grand marquis back about 9 times due to delays in gear shifts? You'd floor it, it'd redline, and then drop into gear and you'd leave one niceee lonnggg black line from the back right tire lol. Finally, before I destroyed the transmission, they replaced the case. I think they caught on that I was driving it as hard as I could until they finally fixed it, in hopes of it blowing up and them replacing under warranty.

I can't imagine that they'd forget to flush the trans lines though. I'm probably going back some time this week to ask why trans fluid is dripping all over that mount. I wanted to change that mount today... but didn't get to it.



There it is... if this is the wrong trans (which I see it doesn't match), then do you think there'* anything I can do?

There you go.

Your car originally came with the 3.06, which is the sporty performance ratio, and the one they put in it has the 2.86 granny gearing. If anything, find a 3.06 tranny and have it put in, as the current one is a bad base to start off with if you plan on modding.

Trans shop is retarded. I wonder if I can get them to believe the whole transmission being the wrong gearing is causing all these trans issues. lol.. that'd be great. I'll have to talk to him some time this week.

Yes, you can. Your shift points in your PCM are set to a 3.06 ratio. Your trans SHOULD be acting not only sluggish, but generally retarded as well.

That'* awesome, in a way. Makes me happy, and understand a lot more why my transmission acts like it does lol. Sweet, I thought I was just being over-perfectionist. That'* what my girlfriend says.

Now all I have to do is fight with the warranty company! Sweet...

I believe they owe you a loaner vehicle as well.

Yep, that comes with the warranty. Typically is an older hunka junk, but it'* typically a Buick. I don't mind driving another 3800 til' mine is done. That last buick I had would have smoked my car I duno wtf was done to it, but it was a 95 buick lesabre. Nothing on the low end, but man if u stomped it around 25 mph you could squeel the tires lol.

95 LeSabre'* had 2.84 gears typically, but the L27 (yup, the LS had that in 95) has a stronger bottom end than the L36. That'* what they were built for.

Absolutely keep us updated. Keep your cool, but be firm. If you hit a wall, come back and we'll give you some ammo.

Alrighty. Do we have anything that I could take to them direct from GM? Like an explanation of RPO codes, and then show them the tag on the tranny and be like whadafuxup wid dat?

I just have a feeling they're gonna say 'Weellll, just because you have the warranty doesn't mean you're going to get top end stuff'. I'm just going to explain that I bought the vehicle because of it'* sporty acceleration and performance, and that is what was originally equipped. Also, I'm now conforming the rest of my drive train to match the lesser sporty transmission. I want original equipment, or give me the cash and I'll find a transmission to put in myself.I still have like 24k mi left on the warranty, and like 2 and a half years.
