Just as the title states (except I'm looking for NON OEM converters ONLY).

Thanks in advance.

Yes
It usually happens when someone touched the clutch plate with their fingers ( no gloves ) before bonding. Body oil contamination will not allow proper bonding. There can be other causes also.

Is there any warrantee on these, and if so is it X amount of time or miles? And if there is do they cover collateral damage?

Yeah, I took it as if there was oil on the clutch material before it seated against the steel, it would not seat correctly. thats what I get for thinking;) These new wool impregnated, sheep skin bonded clutch's from mike, should fix things right up.

Whos converter, when and from whom did you buy it?

To clear things up, this was originally posted as a general question. I believe Mat said something about clutch delamination in my converter, but I have not spoken with him face to face to verify. I just got back from Texas and only talked to Mat briefly on the phone.

When I spoke with Mat's brother on Wednesday, he stated the tranny was all set and that they were waiting on the converter. I believe Mat said he sent it out around the 10th, so as you can imagine I was a little bummed that the converter was still at PI......

I took it upon myself to call Precision Industries on Thursday and see what the situation was as I've been without my truck now for 5 weeks. At first they could not find the converter, and I gave them my name, Mat's name, and Mat's business name. The secretary asked me to call back and when I did in the afternoon she said she had found it and would have someone contact Mat to let him know what was done to it (she did not know at the time) and that they were shipping it out that afternoon.

Mat called me later that night and said he heard from PI and that they had said I called, so he gave me an update.

It will be 6 weeks without my truck which I use daily. On good days I have been riding my motorcycle to work (even back when we had 29 degree mornings :banging:). I used my 80 a couple of times but with a 25 mile commute and a rig that gets 6-7 MPG using premium, that put a hurt on the wallet. So I have been bumming rides and borrowing vehicles for the last month which is never any fun as I'm always at someone elses mercy.

Now to answer your question Mike:

I bought the converter from Merchant back in June 07. I asked for the 1057 but his secretary forgot to put the order in (made the appointment 2 months in advance of Spring Fling), and when he pulled the trans out the Monday following the event, all he had was the PI converter (I'm pretty positive it was the one Mike L "designed" but there is no "model number" on my invoice from him, just a line that states "competition level converter").

Merchant said he was running it in his truck when it put down 800 to the rear wheels and it would have been an extra days wait and price increase to overnight a 1057 so I went with this one. I did not have any regrets at the time as it was a nice converter and did everything I wanted it to do.

I had no complaints about the tranny or the builder as it has worked perfectly for me. It just sickens me to have paid 4K plus for a built transmission and then possibly have to shell out more due to a possible bad part. Due to the piston issues I have been babying the truck with the stock tune except for truck pull days, so I know it wasn't from "abuse", but it has lasted longer than 12 months so it's a very tough situation....

If I killed it doing stupid things, I could understand and would eat it. I also understand that stuff happens, but for some reason it always happens to me.

So, to repeat, I'm not 100% positive this is what happened, but I believe he said something about it and was curious if others have seen something like this and if so, what I could expect as far as warrantee coverage or if I should buy stock in Vasoline :D:D

i hope you where giving the tranny time learn when you switched the tunes for pulling.

Yup.

Due to issues with my truck (several documented posts over on DP about ECM locking up when trying to load a tune via Predator or EFI Live and truck not starting for days), I ran my truck pull tune a day or two before a pull and drove to and from work and pulled it out the following day. By the time I hit the pulling track the tranny was all set. I hauled my other truck to/from the pulls and kept a close eye on the EGT guage. The 06 tapshift and tow/haul made it a non issue. I knew not to floor it with that much power and a trailer behind me. On flat ground and a light foot it was a non-issue. In the hills, a light foot, leaving it in gear longer and/or preventing an upshift was all that was needed to keep the EGT's low. I was so worried about the motor/pistons and trying to keep them happy, that I'm sure the trans was not even worried about it.

I hope I'm not coming off as angry/upset.

I do wish I had my truck back and I won't lie to you, it does suck as I thought the tranny was the least of my worries, but that's how my life goes...

Since Dec 12th, I think I have driven my truck 2-3 weeks tops as I was involved in an accident and everything that could have went wrong at the body did (12 tries to match the paint, 2 different hoods, no DRL's, etc.) then 20 minutes after I got it back from them, it went on a flatbed ride back to the shop as the MAF was damaged.......I should have known after my truck was 1 hour old and had 23 miles on it and went into the shop for 3 days (glow plugs) that it was going to be a fun ride.

At first I thought the tranny going South was accident related as the timing between when I got it back and when it crapped out was so close. If that was the case, I was hoping it might be covered by insurance, but that doesn't look like the case now.

If it turns out to be the TC clutch, now I have to deal with it possibly being out of warrantee and the truck being at a different shop than the one I bought the converter from.

Luckily you folks here and especially Mike L. and Mat have been doing whatever they can to help. I'll probably get frustrated at times (and it may show in my posts) until I get my truck back and running right and may even ask stupid questions, but I do appreciate everyones support.

So far my biggest complaint with anyone is myself for having bad luck. Once the dust settles and if we can pinpoint exactly what went wrong and how it's handled, then I might get a little mad, but I don't want to jump to any conclusions as if I did in the beginning, I would have most likely been dead wrong.

Well, I just got off the phone with Mat.

Yes the converter clutch delaminated.
They covered the converter rebuild/fix fee, but we still paid to ship.
They also sent it back ground :mad: (I would think they would at least try to help us out and send it back overnight). As of this morning the converter was not at the shop yet.

In talking with Mat I guess I'm SOL about them covering the damage the debris from the converter clutch caused inside the transmission :buttkick:

I don't mind paying for Mat's time (it was not his fault the tranny failed), or for the C3 oiler I'm having installed (as that was unrelated to the failure), but I'm a little ticked about having to pay for clutches, gaskets, seals, etc. that needed to be replaced due to the converter failure. Am I alone on this?

Back when I was 17, I had my tranny guy do a TH350 for me. It was a basic rebuild with a shift kit and a few mods and a new converter in my 1980. 3 weeks after the converter self destructed and sent crap throught the tranny (pulled the pan and it looked like fine beach sand but metallic). He pulled the tranny found a bad converter and called the company. They replaced the converter and paid for all parts (he threw in his labor as he felt bad for me being a high school kid with little money). That same tranny is still going in another truck almost 16 years later. Originally I was going to have him do my Allison, but he point blank told me he had zero experience with them so I opted to go elsewhere (no hard feelings on either side) and I still had him due the TH400 that's in the 80 now.

What do you guys think?

I think you should go after PI to at least pay for the parts for your fix. If they accept blame for the trans going bad, they should accept blame for all it took with it when it failed. Sorry to hear you're having such rough luck with your truck. I know how it feels.

wow, man, I had high hopes it would've been accident-related and you'd get reimbursed, now I had high hopes it was converter failure and you'd get reimbursed. I don't know what else to say other than I hope we can find out what Precision's warranty policy is before I buy their converter. I can give you a ride down later this week if you need me to.

I may need to take you up on that. I had originally hoped to ride the motorcycle down and load it in the back but Mother Nature seems to have other plans for me the end of this week. I will keep you posted and once again, thank you.

Anyone have similar experiences? I don't want to go over Mat's head as he is the one doing the work and was the one that sent the converter out and talked to their tech guys (I just talked to a secretary to find out where my converter was), but I don't want to eat this if I don't have to.

I don't think Precision produces a bad product. The numbers speak for themselves and there are guys pushing the converters alot harder than mine with no failures that I know of. Again, it's just my luck. I did however hope they would help me out a little or offer to help Mat (or myself) out with the other parts.....

Tim, I wouldn't not buy a PI converter because of my failure, but I would definitely find out Converter warrantees (and fine print) if I were you.

I don't know if I would be in a different boat if I had a Suncoast, Banks, ATS converter etc,. It was something I never thought about as in the past I was taken care of....

look into suncoasts warranty as well.... because you normally have to pay for a refresh unless they deam that your converter is "outdated" and then they just give you core value for it....

pm me if your curious of the other details
