Spoke too soon! Upgrades? 4T60-E

[3400-95-Modified]

called it! DING!


I would double check to be sure the 1-2 roller sprag is the borg warner unit... Unless thats been rebuilt then it doesnt have that version in there, and since its a pre 96 it also doesn't have the newer style they introduced.

here is the most visible Carnage pic.... Reaction shell.... Hill Billy version (toothless!) Also alot of play in the bushings, the splines on another part has its teeth are about stripped (not sure what its call)... Ohh and the Chain has about an inch of slack/play in it.

EDIT: Nice, now the pic isn't showing up over here...

Ohh and i forgot to mention im getting a High stall converter on the rebuild.. but on a good note, there was a few things showing heat but not really much signs of burnt internals.

Is that because you have a good cooler? If not, I would for sure invest in a good one. It will keep the rebuild happier longer.

[RedZMonte]

Yep i run a large B&M Super cooler

Probably stripped the teeth on the 4th hub at least thats the other part in the picture, but with how much damage is done to that reaction shell, I'm wondering how much damage was also done to the planet assy and the 2nd drum since both of those are what the shell interlocks with.

Dont be so sure.

To point away from the Forward Roller Clutch, I venture the filter became paritally obstructed as the reaction drum wore, and then completely once it blew. Also the then highly concentrated metallic trans fluid probably compromised the pump system some.

Mechanically the reverse reaction drum is not effective in 1st gear so without the drum even being there at all, he should've had first gear at least.

Make sure they clean up and blow out that case and valve body thoroughly otherwise you'll restrict the soleniod filters in short order.

I think your missing my point. The 4t60e had a very poor design for the forward roller clutch. I did not say that caused his failure. His failure was due to once again poor design on parts. Neither the reverse shell or the 4th hub splines are hardened from the factory and they wear in a well oiled transmission or not. Note my pictures, that's from a 74k mile mother driven car with no trans issues.

So what I was saying is to take apart the forward roller bearing and inspect it and replace it with the Borg Warner unit since 95% of them fail. I put a brand new original designed one in and it failed in 10k miles, I put a Borg unit in and it's lasted for over 75k with everything else the same.

I certainly don't miss my auto...

He was using a stock 4t60e with boost... what did you expect.

[gpse3400]

Not for nothing, I think there is something to be said about a stock auto under extra rated load that died at almost 150k. Not a bad life.

[pocket-rocket]

Well, don't take my opinion the wrong way. I certainly didn't expect it to live to see 150k. Especially since I went through blew 2 4t60-e transmissions myself. Besides, I'm more partial to rowing my own gears when it comes to personal preference. I just don't like automatics (especially FWD automatics). Too complicated, too heavy, too expensive with all of those parts inside, and chances are, if there is a problem you have better odds of getting home in a messed up manual than you do an auto. My truck got me home while stuck in 1 gear while driving in another gear (broke shift lever probably, since it would try to move in neutral), where as I got stuck in Chicago in the 91 when the transmission went out. Like I said, it's my personal preference, so don't take my comment the wrong way...

[gpse3400]

Funny when my 284 shit the bed it left 40 miles out in the middle of Pennsyltucky....

I think its fair to say when a transmission goes it goes, and there is not a fighting chance of an advantage to slipping it home (in the case of an Auto) to grinding, binding, and in some cases slipping it home (in the case of a Standard) versus not going anywhere at all taking into consideration all the carnage that will take place by a forced movement. And further more Automatics are pretty straight forward once you learn how to deal with them, no different than a Standard which has quirks and surprises all of its own to say the least. No different than anything else really...

I have no preference just so long as the damn car moves, but you already knew that...

I just like Power braking to build boost . My old TGP was awsome at it, 10PSI before the light turned green..... RRRRRRTTTTTTTT and i was gone lol.. I like manuals on a performance type car (my STI, Corvette, Ect...) but on my DD hoopty i prefer the auto.... lol and i only have to spool the turbo once and im at full boost till i let off.
