Ever since I got a complete ATS tranny installed my pickup doesn't like to run in t/h. Most of the time when I mash the throttle in t/h the transmission will "hang" in a gear. It won't shift to the next gear untill I let off the throttle. But it doesn't seem to do this with t/h off. Is this normal, or is something messed up with my tranny?

I have had ATS try and check it out, but the time they did the transmission shifted fine. Go figure. Then they just gave me the run around and told me everything was fine, like I didn't know what I was talking about.

Could it be that t/h mode hasn't learn and adapted with the extra power I am making? How long should it take to adapt and shift properly at WOT?

Probably because you don't run enough in T/H and it needs to learn. YOu might want to have the taps cleared and start over.

:exactly: My SC IV took for ever to pull the 3-4 shift in T/H together.

I had to recently reset my transmission and go to the FAST LEARN for all shifts, as I had some weird shifts myself, all is good now...........;)

I think programs have something to do with this. Clear TAPS and put the TCM in fast mode with Tecvh 2.

Very valid point Mike L. Some programs behave way better then others.

Assuming you have not overlooked the simple things and the fuel filter is fresh etc?

It seemed like my truck took forever to settle down in T/H after Mike did the tranny. Now that it has "learned," I am able to change power levels, etc. with much less effect on shifting.

This Alli still confuses the hell out of me sometimes...

What kind of programs are you using? i.e. va, tts, edge. Do you have a copilot?

At times I have similar issues.

Well I would have thought the transimission would have learned by now. I don't drive in t/h all that much but usually when I thrww t/h on it was because I was either gonna pull a trailer or I was accelerating rapidly. I have had the complete tranny and co-pilot installed for almost a year now, and it still acts up and doesn't want to shift. I have had the taps cleared a couple times, and also had it put in fast learn mode, also the fuel filter is fresh. For a while I ran my truck in t/h all the time and drove the crap out of it so it would get use to the power and shift correctly, but the next time i took it to the track it still didn't shift right. So now I pretty much just don't ever run t/h and it seems to be okay.

Currently I am running the new PPE Hot program. At first when I got the tranny I thought it just needed to get use to the fact that I added more power. But it still doesn't want to shift correctly all the time. It is pretty irratic about when it will shift correctly or when it will hang up in a gear.

do co pilot settings, it being off, or it being totaly disconected change things at all? What are your co pilot settings at were it does this? Do you have the lil wire that gets soldered done right?

Having the co pilot off doesn't seem to help it shift any better. I think it just gets worse, and wants to "hang" in a gear much more often. I have the co pilot set on the most aggressive settings all the time. ATS told me this would help the tranny learn this settings and then when I go to the track it should be ready to race.

I did not solder the wire on to the back of the dash like the instructions say. I did like some have done on here and wired it to a ground with a switch. Then when I throw t/h on I flip the switch on.

By the way. With the co pilot on the most aggressive settings should it really bang gears hard? Mine doen't really shift hard like I thought it would. I imagined after all this upgrading to the tranny that it would really shift hard and quick. It seems to shift some what fast, but I thought it would be real aggressive like when shift kits are installed in cars etc...

It might be because the TCM has already "learned over" the co-pilot. I believe most have found that the best way to use the co-pilot is to leave it off until you want to race.

In 2wd mine will shift so aggressively in T/H with the Co-Pilot set on kill that it will even bark the 3-4 gear change.....I reset mine because the shifts were all fine except the 3-4, it was a little lazy........if you did the full FAST LEARN with the TECH 2 it should have cleared the shifting up for you.

It might be because the TCM has already "learned over" the co-pilot. I believe most have found that the best way to use the co-pilot is to leave it off until you want to race.

That is the advice I was given, and keep it out of T/H as much as possible.

I have always thought that was the best method to use as well, but ATS told me that was the reason it wouldn't shift correctly when I went to the track. They told me to leave the co-pilot on all the time so the tranny could get use to it and shift properly.

If I leave my co-pilot off when I am just driving around should the transimssion shift okay? It seems like with out the co pilot on it really wants to hang in 4th gear and not shift into fifth when I floor it on the highway. Or does it do this because it hasn't learned, and after a while it will go away?

By the way, thanks for all the help and advice. ATS just gave me the run around, so I appreciate you guys trying to help me out.

are you running the BIG VA for a tuner.........if you are that's your problem.........

if not, tell us what you are running for a power adder........

GMC 2002....I'm pretty sure he said he was using the PPE hot box

I run with my co pilot set about mid way all the time.

Are you talking the downshift4-5?

Do you have acess to another high HP program to try? I dobt it but it may be something to try I suppose.

I have my TH attached like you described and its fine. Maybe have ats play with it again? How did you attach the wire for the boost signal? Wondering if its not getting a real good connection? Duno if it would do what your describing but I suppose its something to check

I am running the PPE Hot Xcellerator.

ratlover, are you talking about the wire that attaches to the map sensor? I installed everything like the instructions said. I guess I could take it off and make sure it has a good connections.

I am not talking about it not down shifting correctly. Here is what it will do: If I am on the highway going to pass someone typically I will throw t/h on and step on it. It will down shift from fifth into fourth gear. Then it will hit the red line and just stay at 3200 rpms in four gear with out shifting. Then when I let off to about 1/2 throttle it will finally shift into fifth gear.

Or if I am making a run from a dead stop it will get stuck in either 3rd or 4th gear, and stay at red line untill I let off the throttle.

This seems to be worse when I am not running the co-pilot, and will almost do it every time. With the co-pilot on it seems to do this less frequently but occasionally with still do it.

By the way, I use to run the tst box stack with the regular PPE xcellerator program. It still did it then, so I don't think it is from their new hot programing either. I don't really know anyone around hear that has a big program other then just running my tst box all the way up with out the PPE on.

Everybody elses trucks shift fine with out the co-pilot on? It just shifts quicker when the co pilot is then turned on? Because I don't think my co pilot shifts that much quicker with it on versus having it off.

oh by the way I just thought of this. The last time I was in at ATS having my truck checked out, they gave me some BS story about a fix they had for it. Said that they have noticed this problem and they are just coming out with parts to fix it. For another $1800 they would fix my shifting problem.

How nice of them I spent over $5000 there on a tranny doesn't work for $#!+ and I am suppose to give them another $1800 for them to try some experiemental parts to fix it. Ya right!!!

The PPE hot is available in 2 forms.Normal and no defuel at shifts.If you have the no defuel program it takes a GOOOOD trans and alot of learn time.

If you have the new ET ELIMINATER tune it will test your patiance , it will slamm 1rst and miss 2nd while learning, and rev before shifts, but I have had this tune for a month and my trans is just getting used to it ,as it does not defuel at shifts ( kind of like a old carb engine at WOT the trans has to just grab ) it will always let you know it is there as 1rst gear at slow speeds damn near chirps um, however at WOT you lose no boost between shifts,

I am not sure if I have the normal or the no defuel. I told ppe I wanted it with no defuel between shifts, however I don't think I got that because it quits smoking between shifts. Can you tell by the program version number?

So do you guys like the Hot ET Eliminator (which I assume is the no defuel between shifts?) Or would you rather just get the regular hot program? Is there much difference in you 1/4 mile times, and is it gonna smoke the tranny? I have an ATS tranny with the co pilot, triple lock, and c1-4 clutch upgrades.
