Do your homework on this company... start by searching that name here at Tech. Many people were left in a bind when they went under a while back. Without all of the drama... Dave had some personal issues that caused the company to crater. It happens.

He builds a pretty good unit. Lost touch with him very early last year after his shop closed... professional type relationship, we compared notes on 60's a couple of years ago. I pulled up his website and dialed the # on the contact page.... busy signal many times. Lemme know if you talk to him, I'd like to say hey to him again.

Are you serious? I have a rock-on tranny and it just went out after almost a year. I tried to call Dave and noone answered. Are they seriously out of business?!

Rossler is not a sponsor here but builds a very badass 4l60 unit. They are a stable company that has been around just about forever.

Before RockOn ran into $ problems they were numero uno.Those trannys could take loads of abuse.

I have seen 9 sec.F Bodies with there Trans(4L60)with no problems.

I have one and its the best trans I have ever installed

Gilbert@Ace Racing

I agree.

In their prime Rock On was hard to beat.

We have been into a few of their units that had problems and they are solid.

From what I understand the quality fell off significantly in like say the last 6 months of operations. Prior to that, they were serious about what went into their units. You won't hear anything negative from me about them. I talked to Dave on more than one occasion after he had his troubles and I know he did the best could could with what life handed him. That doesn't mean some guys weren't left holding the bag, it just means I sat and talked to him about what happened in the end, and I learned from his mistakes. It wasn't pretty from what I heard from him and some of his customers. Bad ole deal there for everyone involved.

I got screwed by them.

I had mine for ~500 miles and 2/3 bottles of spray and it went out. I ended up losing 3rd and 4th.

Still had warranty as it was only 4 or so months later. Tried to get a hold of Dave at Rock on and they went out of business a week after they overnighted my tranny and did not even want their box back with my core. Seems to me they put crap parts in and did not want their box/core to save on shipping charges. I paid ~2G's from wy stage 4 and it was junk.

So, I havean FLT stage V now and its held up to 10 or so pass's and 8/10 bottles of the juice. So, be carefull with the Rock on crap.

Gilbert@Ace Racing

Lot's of stories just like that one out there. Very unfortunate, sorry to hear about it Waterbug.

Sorry man, they went out of business a long time ago It was about a year ago. It sounds like you bought your tranny not long before they went under, and from what I heard, their last batch of units were pure junk, little more than upgraded clutches. Being as your tranny went out in so little time, I wouldn't be surprised if you got one of their "built units" that was barely any stronger than a stocker or worse. I wouldn't buy anything even affiliated with Rock-On. They screwed a lot of people towards the end of their run

Rock On still post on the camaro z28 forum and is still in business from my understanding or recovering anyway. From what I gathered from reading it was just a case of to much to fast and personal issues that caused there issues. Maybe post there if your looking for answers. I dont know them personally but that what I gathered from reading. EVERYWHERE!

Well, if they are trying to make things right they ought to get back on here and straighten some **** out.

I would like to get my ~2G's back as the tranny was garbage and the warranty did not mean ****.

I sold the box and the core so no proof of even owning the trans now.

Sorry for your missforune I was just letting people know what I have seen on the various forums.

waterbug1999

iTrader: (3)

They know who got the raw end of the deals at the end of there "going out of business sale"... Maybe the moderators on here wont let them back on cause they screwed over alot of people on here.

performabuilt

iTrader: (25)

True but maybe you should try a post over on the camaroZ28.com forum or a PM hey maybe he will try and do something you never know till you try. Just and idea.

Im sure if he/they started handing out refunds for the POS trans they shipped out at the end of their run, it would have made it over here at least.

Was just making a suggestion as I said I know very littl about them I think I have PMed with the guy who owned it or someone who worked there a few times. I do not know there present general status. I just know I do see them post over there periodically
