Transmission problems!

[aceromero1]

I have a 2003 yukon xl with the 4l60e transmission. When I was towing my trailer with my rzr on it up a hill my rpms topped out and I could only go 40 mph. I pulled over to let it cool down. After about a hour I tried to go again and it would only go about 40 mph and seemed to be stuck in first or second gear. Has anyone had this issue and if so what might be the fix. Hopefully I don't need a new trans.

Need some more information. Was it in 1st or 2nd gear when the RPMs started going higher than they should be at normally? On the second try was it level ground?
The possibilities, You were "in 2nd gear" but it wasnt there. More specifically your 2-4 band could be burnt up and is needed to get 2nd gear. Anything from a solenoid, 2-4 servo cut oring to 2nd gear valve stuck in valve body. You could have been in 2nd gear but 3rd gear wasnt there then the valve body comes into play for 3rd gear.
Stop revving it up to get it to move. All its doing is burning up your clutches. The damage may very well already be done which could require a total rebuild. Whats your fluid look like? Pink or brownish-orange? I bet it smells burnt.
At this point you are probably going to have to take it to a tranny shop. Transmission almost never fix themselves and heal overnight. Unfortunately.

I had the same issue happen to my 03. Bad news. Mine is going in for a rebuild. It was whining out in 2nd, wouldn't shift, and the fluid is brownish.

Thank you for your response. I found that my 3-4 packs where burnt. It's in the shop for a rebuild with heavier duty clutches and torque converter. They are building it to give me more torque and bigger trans cooler!

Just curious what did you pay for rebuild or did you do it yourself?

It's still in the process. It's gonna cost around $1800.

Nice that's not bad! I live in las vegas and with all the upgrades it's going to cost about $2600 taxes

Wow! I thought mine was expensive!

Wow. Inflation I guess. A standard R&R for a 4L60E here in the midwest runs right around 1200-1300.

Like you said, a standard rebuild. I'm getting a much stronger build: vette servo, shift kit, beast sunshield, 6 gear planetary compared to the stock 4, etc, etc.

 

[rockola1971]

Vette Servo $20 Shift kit $45 Beast sunshell $80 6 element planetary $100 Hi energy clutch kit with steels $200 (that price is built into the rebuild).

Might be a good deal in New Jersey but my point is...It aint here.

I didn't think it was a great deal, but it needed to be done, and since I don't know how to build transmissions.....

If they dont have it back together yet, id have them install a kevlar 2-4 band. Its much more beefier than the oem and is a must for a guy that tows alot. They are cheap. $15 or so and worth their weight in gold when towing alot.

They aren't going to get to it until Monday. I'm going in the shop to go over everything that they are going to do. I will mention that. I will pay to have the best stuff. Can't afford my diesel until next year so i will have to make it the best I can until then.
Thank you.

I put an extra cooler on mine on top of the factory mounted cooler, plus upgrade radiator to a Griffin three core and no high temps at all! Even when I hauled in 97degree AZ weather.
I kept the factory thermostat to avoid false check engine light, if I moved to a cooler thermostat. I'll recommend to all of you, if you don't have a three core radiator or a big tranny cooler, get one!!
Your engine will thank you and so will your transmission!
