Shoot us over a message if you're interested in getting a built trans.

Checked fluid? Solenoids might be full of trash or something

Fluid is fine.

I had been running the SPE Trans tune since Ennis, at the race I thought I had hurt the Trans. You could see in the times and feel something wasn't right. Well the tune was just to rough for daily driving, so last night I updated my mini Maxx and loaded their tunes. Go to take my daughter to school this morning and bam the Trans is acting like this. Did the relearn process and it is still the same.

I have already talked to Wayne last week about a Trans so we will see what happens.

Have you tried a stock trans file? Hope it works out buddy.

Is your trans still shifting funky?

No, didn't have time to reload to stock then retune it.

Is your trans still shifting funky?

Yes, but driving on the highway right now.

Sak. I experienced a similar problem. I went from SPE tune to the new H&S tune to test it out. Did the relearn process. Then parked it at home. Took the family out to dinner and it started doing that, it was bad enough where I had to take my foot off the pedal and put it into manual to get out of the intersection. A few more times of that and it hasn't had an issue since.

That's weird... Wouldn't think you could hurt the Trans after seeing H&S putting 884Hp 1680FtLb on it with 40"s. Might try to completely clear your SD card then reload the tunes on it and then reload them to the truck. Hope it's just a bug in the down load of the tuning and not really your tran going out!

500 on the street is probably more stressful than 800 on the dyno

I don't know a whole lot about these transmissions, but someone let me know of this is possible.

Is it possible that the clutch packs get pressed together from the pressure and when you go to a tune with less pressure the packs are not coming apart and allowing them to function correctly?

Very true street is more stressful but I also just remembered Bentley at H&S did say he had to raise the line pressure and Torque converter lock up a lot over the standard H&S Hot tuning when they were making those numbers. How many miles you have now Sak? I know you are running 38/15.50's and you pull trailers with heavy loads. Might have finally done the tranny in? Hope not though! :shrug:

If they are stuck together then they would be smoked. Basically you need to run a tune that worked before. If it still shifts funky with the known good tune then the trans is hurt.

The trans did slip at this power level and only made a few pulls at that. The trans are super stout but a quick dyno pull is nowhere near as hard as continual abuse.

Odometer reads 764cc, its more like 83k.

Reason I asked the previous question is because just like bricewise said it seems like it is not acting up now.

I still believe the Trans is hurt though. I don't see why it would act this way

Agreed dyno is not equivalent to daily abuse! Although the Trans slipped on that run. They took it to ATS dyno days less than 2 weeks after that and made 6-8 more pulls on their dyno at 800Hp on the same stock tranny. All I am saying is they are hell for stout being in stock form. Especially seeing that the Dmax Allision slipped at 580Hp on one pull! Lol

 

[SAK]

Well spoke to soon, parked my truck when I got to work and drove my work truck for the rest of the day. Well I just got back in it and it is still acting up. FML.

Wrench light just came on, it will not shift into 3rd, it will hold 2nd til about 2500 under light throttle and go straight to 4th.

In for the clutch pictures. I bet you smoked them
