Default Auto trans rebuild time?

Okay guys my trans has just slowly been going away for the past couple of months, shifts okay but slips horribly I got beat by a stock 7.3 the other day anyways its starting to come back to life and isnt slipping near as bad. I drove the **** out of it yesterday and got in it today and the thing feels way better. Is there any way I have so much grit in my fluid that its gripping more? I know im rambling and it sounds stupid but I just want to know what would cause this.

Let me see if I understand this correctly: Your transmission has been giving you trouble for MONTHS, but you raced your truck the other day? Am I the only person who sees something wrong here? Have you checked even the most basic of things, like: Is the fluid level correct? What does the fluid look like? If your truck has a manual kickdown linkage, is it adjusted properly? If you don't know the answer to any of these questions, or don't understand what they're about, stop racing your truck and get someone who knows what they're doing to look at the transmission. I'm sorry if I come across as harsh here, but if you race a truck with a slipping transmission you're basically formally requesting in writing to have the transmission fail on you.

I can promise you this: If it fails and you have to foot the bill yourself, you will have a newfound respect for both your truck and the cost of abusing it.

The trans is stock with 185k on it. It went out completely the day after I posted that. I guess its just one of those things that runs its best right before it goes out.

It must have been slipping something terrible to get 9 mpg. Hopefully it didn't eat a bunch of hard parts up when it went.

yea i had mine rebuilt at 165k got 242k on it now and everything seems to be smooth! But here is a tip, when you do get it rebuilt make sure and do it right, and put some heavy duty parts in!
