Just curious how many miles some of you guys were getting out of this engine/tranny combination without driving them "too hard." I'm assuming most people's tranny's have died first.

You assume too much. Yes, there's been some blow outs, but I don't over 50% of the members have.

I had my Cutlass DOHC with the 4T60-E and lasted (original tranny) to 174K miles till I sold it.

I did run the RPM's up close to yellowline on some days, but with no engine modifications... something to keep in mind.

Is the 4T60E what is used in the 3.1 Century? If so, mine went about 110K before it gave up the ghost :( It was a good transmission. GM's trans-axle is much smoother than the Ford version. Shits a bit quicker.

310,000kms on both engine and tranny and the whole thing still purrrs... Slight hesitation on 2nd but that's about it.. low end still solid.

 

Do the usual maintenance and upkeep and these things will last long long time. The rest of your car will probably fall apart before they do.

had mine 2 mos, put 10,000 miles on it for a total of 164,000 . Tranny is showing early signs of dropping 4th, but prev owner didn't do ANY maintenance. Also replacing intake gaskets on my 3100 right now for possible problem( see other post titled Since we're on temps ... kinda) but other than that she's fine. hits over 80 mph often thru the week due to living near nowhere, been a week or two since she was over 100 mph. but still a good car til the temp thing.

Just rolled 139,000 miles today. I deliver pizzas in it and beat the shit out of it, manually shifting half the time (I like the sound of my CAI in first @ 35 WIDE OPEN) I have an intersting 1/2 throttle 1-2 shift, kinda sounds like the cradle is going to jump right out the front of the car, (w/ a bang of course) Other than that full throttle/ light throttle no problems. I just keep telling myself that the tranny is going out to motivate me to finish my 3800 S2 Turbo.

i bought my car @ 111,000 miles, and the 4T60 was in there unitl i did the 5-speed swap at about 165,000 miles. i too deliver pizza like mad and i'm all about 'getting there' ASAP with the auto and now the manual too. :) the first thing i did after i bought the car was have the trans flushed and filter changed. since then the tranny fluid was brown but it never gave me any problems except a very harsh downshift when i floored it. altho i never had any real problems with my 4T60, i don't miss that thing at all...
