mines stuffed, its gunna cost 5K to rebuild, was doing skids in 2nd gear and it let go (no surprise). just dont know if this is cheap for a complete unit.
ive stuffed the clutch packs in 2nd and the plastic in the centre has gone through the plantery gearset and chewed out the gears (i kept driving it for a while), i warped the pistons, and the clutch drum is stuffed. basically i need another trans to fix this one.
he bought the trans for a customer (owns a workshop) from a wreckers about 6 months ago, the customer wouldn't come through on the payment (endless bullcrap stories) and obviously he cant return it, so he's unloading it, he pulled it out of the smashed car himself to make sure it worked fine and has had it checked by a trans workshop and it's been given the all clear. he can't remember exactly what he paid for it just that it was around the 3K mark. trans doesn't have any leaks or sweat marks, and the fluid that was dropped out of it was clean (i saw it when it was done)
i've tried calling a few places but no one can give me a firm price on what they are worth with similar K's. most are saying they dont know.
5L40E ? That must be an SV6 am I right? As far as I've read of the 5L40E transmission, it's very well known to fail at around 150,000 km in some model of cars. Don't know if this is true for Commodores, but he might have abused the car and is trying to get rid of due to this potential gearbox problem (or God knows what). As far as I've seen from the other threads around the forum, if it's selling really cheap, there must be something wrong with it. Here's the link where I found out about the transmission.
yeah i expected it to blow eventually, but not straight away, it had only done 57xxx k's
just thought they were as strong as the 4spds, im not complaining but, i just was wondering if i am paying too much for it, i know who checked the trans out and he said its all sweet to me, it just came out of a wrecked car. so the condition im happy with, i just don't know how much to pay for it...
what would you guys pay for a transmission like that? it comes with the converter and fresh fluid and a new filter (old filter was still clean but seeing as the sump was off it was changed, he has the original filter still sitting aside) and as i said the fluid was fairly clean that came out of it, about as clean as i would expect it to be. every where i have called so far only has trans with a large amount of Ks on it and they want anywhere from 2000$ up.
The 4 speed really didnt like downshifts at WOT (eg, floor the pedal and it would kick down to 2nd) as the 2-4 band would wear out quite quickly (thats why a lot of of the 4spds have a harsh upshift and delay/flaring on downshift) also the 3/4 clutches would wear out often. BUT that being said they were quite tough in terms of abuse and rarely "let go" after burnouts etc, it was more that they gradually wore until the poor shifting was quite noticeable even under normal driving.
on the other hand, the 5 speeds are designed to cut fuel and power under full throttle shifting, eg thats why it sounds a bit like a manual if you are accelerating fast and when it upshifts. that will make the clutches last longer as they dont have that strain under full throttle gear changes.
BUT - the 5l40e box maximum torque rating is 340nm, the 190 kw motor puts out - 340nm.
So go figure, as good a box they are, they are probably designed for something smaller than a commodore, put them behind a v8 and they would fail, unlike the 4l60e's which is virtualy the same box on the 4sp v6's and v8's. not surprised we are starting to see them fail after people abuse their sv6's and calais'.
