Been awhile since I’ve been on here.
1983 Convertable—BluePrint 5.0
I’ve put around 4,000 miles on her, and the original C 5 is giving up the ghost.
I’m looking at a Monster AOD hd
Any opinions?
Only 315 Hp
You all have given me great advice in the past, so I thought I would see what you think.

Jasper Transmission, 3 yr 100k mile warranty and they will build it anyway you need.
Thank you
I’ll check them out.
The reason I am looking at Monster
They have the kit with everything I need—Torque converter—cables etc. all for around $1,800.
3 year warranty.
I will check into Jasper tonight.
Again, I appreciate your help.

I'm not one to bash a company but have you looked up the reviews for monster transmission on the bbb website?
No—I just started my search for a new transmission today.
Like I said—Just got off the phone from Jasper.
She said they had nothing that would work for me.
Unbelievable

Well I just called, and talked to Jasper.
Either the person I was talking to was a friggin idiot or they have no transmissions that will bolt up to my 5.0
That was what I was told.
I have never bought a mustang trans from them but I have one in the 'dump truck' it's a SD 73 turbo tow truck and the shop here has installed many engines and transmissions from them, never a problem.
Go to their webpage and find an installer near you, call them and they can help you with finding a phone number that may better serve you.
If you can't find one near you hit me up in a pm

I really appreciate it General.
She apparently could not get it through her head what I am wanting.
I spoke very plane English.

Whatever the hell you do, DO NOT BUY FROM MONSTER.

Below are the excerpts from my Mustang's build/progress thread pertaining to the 4L60E I bought from them for my dad's Suburban:

Spent all day Saturday on my back under my dad's Suburban wrestling out the "original" 4L60E that took a :poo: on him while pulling a trailer back on January 26th. I say "original" because we discovered during the removal process that we weren't the first ones in there (sloppy/lazy GM techs leave all sorts of clues, like a missing bellhousing bolt, and none of the electrical connector retainers put back through), and that the transmission and torque converter we took out were built 14 months after the truck itself (meaning it had a failure under warranty with it's original owner). Doesn't really matter, my dad bought the thing back in the mid 2000s and has put at least 120k miles of the 166k miles the truck has on it, so he got his money's worth from the original trans (for a piece of :poo: 4L60E anyway). All sorts of glitter in the fluid from the old one, and debris in the torque converter. The new Monster trans and Thor converter were filled and fired last night, we'll be going on a test drive with the 4Runner as the chase vehice at sunrise.

Another weekend of zero progress on the II.
It rained Saturday, so I did the subwoofer replacement in the 'yota. Sounds awesome, but I forgot to take pics.
I mentioned the Monster install in pop's Suburban in my last post. It's going back to them after 110 miles of use.
Long story short, :leghump: Monster, and their warranty is bull:poo:.


Okay, full details on the Suburban's transmission:
We installed the thing on March 12, as I posted before. Did everything by the book, hell, I even torqued the bellhousing bolts to spec. Flushed the cooler and lines, upgraded to the Derale cooler in place of the factory auxilliary cooler as recommended by Monster Transmission, fresh case of Dexron VI fluid, whole nine yards.
We test drove it on March 13 a total of 15 miles or so with me following in the 4Runner. No smoke, leaks, drips, slippage, or any other issues. Checked the fluid at three different stops along the way and let it sit and idle for awhile before checking it one last time, fluid level was perfect.
My dad went to go to a meeting in Waco with it, and didn't make it the 45 miles to the meeting before the "trans fluid hot" warning showed up on his dash. He let it cool off in a parking lot for awhile, then gently drove it back home. The "trans fluid hot" message didn't return, but the check engine light came on. I brought my scanner home from work the next morning and pulled a P1870 (transmission slippage) code.
We called Monster, and they wouldn't even talk warranty because they hadn't received our core yet. We wait for a week for the core to get there, down a vehicle yet again, and then they finally contact us back. Their "3-year handshake WOWanty" is as follows:
Monster Transmission and Performance will pay $50 hr labor and will supply the necessary parts needed for the repair at no cost to you or the client if needed.
If you have access to the parts needed, Monster Transmission & Performance may, at our option, permit you to use comparable parts from your inventory. Please submit the part, as well as the price of the part(s) for review/approval.
Please send an estimate via email for repair prior to performing any work to the unit. As previously stated, we do not pay the following:

  • Diagnostics
  • Hazardous Waste removal
  • Removal & Installation
  • Shop fees
  • Storage
If I'd read that particular bit of fine print before ordering, I would've ordered from somewhere else, but they make sure that's buried hell-and-gone on their website, and not anywhere near where you're looking at their transmissions.
We take it to a transmission shop I've done business with before, pay out-of-pocket for diag, and their diag is that the transmission is fried due to improper assembly, that it's slipping in 2nd and 4th and isn't locking up the converter. Their only recommendation is replacement or rebuild.
So we call Monster, and they want US to pay round-trip freight on a defective unit THEY shipped us. My dad gets them to agree to pay half (if I'd been on the phone instead that wouldn't have happened, they would've been paying all), so I spent yesterday afternoon yanking their junk rebuild out of the Suburban.

So, a few pages back, I chronicled the two transmission swaps in my dad's Suburban thanks to Monster Transmission's incompetance.
That particular saga continues.
You see, after I finished the second transmission R&R, my dad pretty much drove the Suburban exclusively for awhile. Well, he parked it for a few days and drove his Hyundai to save gas, and the Suburban leaked about a quart of transmission fluid all over the driveway from the tailhousing seal.
I figured they'd used the cheapest seal they could find, and replaced it with a new National seal, not bothering with their bull:poo: warranty over a $10 part and 30 minutes' work.
Dad drove the Suburban daily for awhile, all was well, and then he parked it for a few days, and it again "marked its territory".
I pull the driveshaft, measure the yoke with a micrometer, find that it's okay, and change the seal again, warning my dad that the next time it happens, we're going to have to take the tailhousing off the transmission and do some investigating.
Yesterday was that day, and what I found has me furious.
Monster didn't replace the tailhousing bushing, a goddamned wear item, while they had this thing apart! It's worn completely the hell out.
Whatever you do, don't buy a transmission from these assclowns.

No vibrations, just the recurring leak. Also found out it's missing a sleeve that's supposed to be on the tailshaft in this particular application that reduces fluid flow to the driveshaft yoke. Monster Transmissions is a :leghump:ing joke.

EFFIN' SHORT VERSION: I'm an ASE-certified technician that works on cars for a living. Dropping a 4L60E out of a Chevy and putting the new one in is child's play for me (hell, I work on BMW for a living, EVERYTHING ELSE is child's play at this point). Installed the first transmission by-the-book, THEIR book, in fact, as they wanted certain things done a specific way "for warranty purposes". The first transmission that they shipped to us failed spectacularly after just over 100 miles, and their warranty replacement had multiple problems until I finally took it apart and found that they'd forgotten a part, re-used a worn-out wear item, and installed an incorrect seal and rectified their errors.

After the fact, I found pages upon pages of complaints about them on the various GM forums... which I wish I'd read first.

Thank you very much for taking the time to tell me about the apparent assclowns at Monster.
Guess my search for a transmission continues.

Monster transmission is JUNK

If it’s an AOD you want call Lentech or Freddy brown . You’ll be into for what a monster would cost and they will live

I have a Freddy brown unit in my car . It is way different then you would need but he knows how to make them live and live a while .

silverfox . Dan knows AOD's better than anyone
Thanks
I appreciate everyone’s input.
Apparently I was about to make a very serious mistake buying a Monster Transmission.
Reason I love this site.
Everyone has given me great information ever since I decided to upgrade the little Fox.
I love driving her.

I had some issues with monster transmission as well. I bought a 4l60e because I had my old transmission rebuilt a few times already. Just looking for a new unit. Came in looking beautiful. Excitedly I put the new trans in. Wrong size coolant lines. I ended up losing a lot of.tkme getting the proper stuff to splice in my lines. Got everything hooked up ready to go and truck wouldn't turn over or show the trans needle in my truck. Bought a battery and starter for the truck no change. Took it to the garage 500 dollars to program to the truck. And found out its the wrong transmission.

So a lot of time passed during this period trying to get my truck to run. Then they tried telling me.i never shipped them.my old core so my WOWantee never got enacted.. fought with them for.several weeks and finaly they agreed to.take back both transmissions and rebuild.my old.core at no cost. So I had to take the new trans I bought out of my truck again ship.it back to Florida and wait for the rebuild.
I got the new trans and been so fed up.with everythjng still sitting in my basement.

Truck has been out of commission since last october.
They did right their wrong but couldn't match the proper trans for.my truck? They were affordable Option but was a huge headache and I should have sucked it up, and got the trans rebuilt at a shop and been back on the road in two weeks. Would not recommend monster transmisson either.
