Durability of FWD drivetrain?
Durability of FWD drivetrain? I've been driving an Impala SS for a few days, and I must say I'm very impressed with the car. It drives nice, has great power, and gets good fuel economy. I'm thinking about getting an SS or GXP for my wife to drive. I would plan on keeping the car for a long time, so durability would be important. I've got enough experience with the LS1 to know I can trust the engine (although the DOD is new to me). What I'm really concerned about is the drivetrain. Does the 4T65E-HD actually hold up long-term? And what about the driveaxles, etc. Any actual owner experience with durability on these vehicles would be greatly appreciated.
Thanks!
Thanks!
I have seen a lot of guys with 40-50K plus on them, they seem to have worked out some of the early bugs. From owning FWD V8 cadillacs for years expect to replace the transmission at least once before 150K, probably twice by 200K. . . the motor should easily last that long.
Yeah they are good for about 100,000 miles before they need a rebuild. Seeing as your wife will probably taking it easier...maybe longer. What kills these trannies is HP and tapshift.
Yes, the 4T65E-HD is a great Tranny and will hold up very well over time IF IF IF you take care of it.
1. Every 2 years, do a filter and fluid change. I dont care what GM says, this will help protect the Tranny and in return it will thank you
2. This is not a manual/stick. Some people on the board like to drop there car into 1st or 2nd. LEAVE it in Drive and let the computer do the work. Thats what its there for.
Good Luck with that you pick out and always remember, we are here for ya.

If you want the trans to last longer no matter how hard you drive it i would recommend getting a shift kit. Shifting harder will save your clutch's. Car makers for so long have tryed to make transmissions shift as smooth as possible selling this as a better transmission but inorder to make a transmission to shift smooth its slipping clutchs slowly. All my cars i've put shift kits into even on my old 89 cutlass oldsmobile and the trans lasted 280,000 miles untill the engine finally gave out. The transmission was on its last leg but it was never replaced.

Smooth shifting trans = slipping clutches! Right, but if you put in the wrong springs in the shift kit and tune your car, you will be in trouble.

I would rather have a hard part fail then have to deal with the agony of a slow shifting transmission due to the clutch's wearing out. Also when do you ever see a hard-part fail unless seriously abused or increased horse power. Its the clutch's that end up causing poor transmission function. But in the end i've seen people who drive there cars hard and people who don't and i've seen all sorts of results from all sorts of drivers. I hope my transmission fails right at the end of my warranty so i can go ahead and upgrade it and trust me i'm trying. I'm going to trade it in for the new Challenger if it comes out before the charger and if it has at least 400HP
Thanks for the info, guys. I'm from the school of thought that somewhat firmer shifts (i.e., faster shifts) are good for longevity. The clutches don't have as much time to wear during a faster shift. Too hard and they're kind of gut-jarring and hard on the drivetrain. I would plan on getting a shift kit (like I did for my 4L60E) and set it up to shift a bit firmer. I've had a lot of cars over the years with auto transmissions and have always put shift kits in them. I've also never had a transmission fail on me! The other thing I've always done is install a trans. cooler.

They are a pretty good transaxle, mine had 110,000 and i'm making about 400 flywheel HP in my supercharged buick. All was good until the TC came apart and took everything with it. If change the fluid on a regular basis, don't drive the crap out of it, you'll get a lot of miles out of it. A built one can handle about 600 -700 hp before they come apart, thats what has limited the fwd cars to 9sec 1/4s. My built one barks gears now
