why is the 4l60e such a P.O.S.?!

[bottomline2000]

I was told to replace everything when my 1st trans went south. If the shop is reusing the same lines it could be something in the stock cooler lines killing your trans. I had all the lines replaced and a big cooler added so whatever broke the old one wouldn't find its way into the new one. Plus keeping the trans cooler seperate from the radiator sounded like a good idea.

TXGMC- the 4l60e was revised in 1999 because of durability issues. My truck is a 97 so i guess you can say i have the ****** model lol. also, does a stall converter put any extra stress on the driveline? And what is a damn "shade tree" mechanic? lol

also, i dont have a trans temp guage, deep pan, or aftermarket cooler, and I have only changed one line because it was crushed. Other than that it is all the same.

Are you taking it to a "shade tree" mechanic? that may be the problem. I doubt that superchips is squeezing out 40lb/ft of torque with just a tune. That old 350 is tough to get power out of (ive heard). Heads and cam might give you 40.

Stall converter allowes your engine to rev higher before all the torque gets to the wheels. For example, I have a 3000 stall converter in my 08 Sierra. It allows me to stall it to 3000 RPM and it'll launch off the line at 3000 RPM. Hard to keep the tires planted though. It got me .4 seconds off the 1/4 mi time.

All my mods on my 08 Sierra are on the stock 4L60E and she shifts just fine. And I beat it up pretty good. I know im gonna have to rebuild it down the road so I dont beat it up as often as I use to. Theres a Transmission shop here in South TX that will rebuild the
4L60E to support 550+HP for just under $1000. Not bad I say, thats what ill be doing to mine.

Where exactly is that transmission shop in the Valley? That sounds like a pretty good deal, and what warranties do they offer?

I would say that may be some of your issue rite there. The factory transmission cooler is just not big enough. I would recomend getting the biggest one you can find and put it in line with your current one. Also would recomend the trans. temp gauge because to me it just doesn't seem intelligent to dump all this money into new transmissions without any way to monitor it?

i have heard this before, but im running my stock cooler with my built trans and 3k stall, and i have not gone above 165*, which is 5* below normal opperating temp...and thats with beating on it pretty hard the last few days in 65* weather..i suppose this summer it may go higher, but cruising on the interstate in at about 150..

True, 97 to 08 have brought a lot of changes. But, that 97 doesnt put out nearly as much power as the NBS GM trucks... Also, all the Torue management in the NBS trucks keeps the trannys safe. But it kills power, thats why I removed it with the custom tune.

A stall converter does put more stress on the engine because you have to give it more throttle and keep it there to keep moving. I put an Oregon Performance Trans cooler 40K GVWR. My trans was seeing 200+ temp after that 3000 stall. After the cooler it stays under 160 and thats in summer heat 95+ degree outside temp.

The trans shop is called Aamatic Transmission located in Mcallen, TX. Every LS1/LT1 F-body and GM truck owner that races and has a trans rebuilt by Aamatic knows Joel or JR (same guy) some people call him either or. Hes the guy that rebuilds them. Matter of fact, when they put a trans for sale on the forum, they refer to it as a JR tranny. Immediately people know its good. Let me know if you want the address and phone #

New trans fluid lines would also be a good idea. Wont matter how much you spend on a transmission and it being the best on the market. If it over heats, its dead. Get a trans temp guage. Good investment. I lucked out, my 08 has it in the menu.

Yeah, give me the info. If I ever need to rebuild mine, I guess I can try him out. Do you know what type of warranties they offer?

 

[Arctic-Rodz]

Im not sure on the warranty....
Aamatic 616 S 23rd St Mcallen, TX 78501
956-618-2020

Just tell them what you want done on your trans and what it will be used for and theyll do it to your needs.

 

[mdiacont322]

So it sounds like the bigger cooler and guage is a smart idea so i will invest... what is the best way to install a bigger cooler and temp guage?

Also, what about a pressure guage?

 

[retorq]

I ran the factory cooler then took the output and ran it into a cooler in the front of the condenser. Nothing too fancy, used rubber lines. Temp gauge can plug in there or run into the pan. Pressure gauge is a lil more tricky.

 

[bottomline2000]

Well Jasper Engines gave/sold me a 3 year-100k warranty. I haven't seen anyone offer something like this. they aren't the cheapest, but I have put about 10k miles on it and it shifts like new and they threw in a shift kit which makes for all the more fun. I could have gotten a high end built trans from any other place for the same price, but I didn't want to deal with spending $1k to have it pulled and shipped everytime something went wrong. I got a zero deduct warranty that covers all kinds of crap if something goes wrong.

 

[drifter666]

Ive burned threw a 4L60e in an s10 blazer cost me 2k to rebuild it with a 2yr 24k mile warranty although I am in the north east I'm sure I got ***** considering it is all stock and i think its going again. One thing when you repair something ask for the old parts that way you know they didnt just "put something BACK"

What about an extra filter on the return line would that help also?

I have seen guys run and external filter (or remote filter Kit) and ditch the one in the trans (some kept the one in the pan). I think they had to run bigger lines and make a custom pickup tube. Not sure though.
