Monster Transmission?

My transmission took its final trip. I have a 96 ProCharged LT1 with a 4L60E transmission. Car produces 450 ft-lbs torque at the wheels from basically 1500 rpm to redline. Looks like the 3-4 clutch pack went bad, most likely from my blowing a tranny cooler line at highway speeds and running the thing darn near out of oil last fall. I’m looking to replace the stock tranny with one from Monster Transmission based on some internet searches.

anyone have experience with them? I like that they come with a new torque converter and a 3-year warranty. I can’t find anything really good or bad about them. Monster Transmission

thanks!

I have heard really really bad things about monster tranny. They are expensive too.

Thanks for the input!

You're setting yourself up for 'maybe' certain disappointment. I'd do nothing without first doing some more serious 'local' conversations! Your posted location hints there should be serious options available within a reasonable drive! reasonable drive = local!!

But in post #3 you said exactly that .. OR so it was most likely read by many/most! Reasonable drive/tow says much for diagnostics/issues into the future. Many 'performance' builders prefer to or insist it's their install! Procharged and an 60e build that could be quite valuable!

I used their 500hp kit to rebuild a 700R4 in a 84 Trans Am and it works great. Cant speak to their complete transmissions however.

How do they do warranty? Something I had before when you get a kit and someone else builds it and things go south. Builder blames parts and parts blames builder. You, OTOH, get screwed.

Ask me how I know.

All were successful and I am no means a pro.

Art Carr was a complete *** when I tried to ask him questions about different parts. But the 2004R works great behind a 450hp 383 gen 1 in my 81 trans am. He also sells parts for the 700R4.

Get a good torque converter. This is almost the most important and overlooked part. I'd suggest ~ 2500 rpm.

I don't want to build a transmission or engine myself. I have installed those with a cherry picker and definitely don't want to do it again. Way too miserable trying to get them both in at the same time. IF I didn't, not sure how to take the transmission from below without much room. Fortunately it was on a different car that was easier looking. Connected trans to engine and angled it in and kicked myself for doing it alone.

One thing about Rossler is he does not like to build it and send it to you and at some point, you return the core. He prefers to rebuild your junked trans.

So I went to 2 highly respected speed shops today and both recommended the same transmission shop. Looks like comparable build to PerformaBuilt level 2, similar price range. So it looks like I’m going local after all. Thanks for the input!
