What would you pay for 4L60 Monster Transmisionn fresh rebuild?

I bought a Monster Transmission 4L60 - which failed about 5 miles after install. By "failed", I mean it began to shift erratically and then began to slip. My local mechanic shop could tell me only the "it's something internal". Their local rebuilder quoted - sight unseen - $2K to go through it. Since I did not want to wait a month, or more, and pay shipping to return the transmission to Monster, I bought another one locally and had it installed.

Because it was more than 30 days from the purchase date, Monster will not take it back and issue a refund. They only agreed to fix it and return it to me - at my expense. Since I no longer need it, I would then need to sell it. I'm trying to determine what I could reasonably expect to sell it for. And, whether it's worth the hassle. The retail from Monster is about $1800.

Unfortunately without a diagnosis it's probably not worth much more than a core charge.

Get your transmissions rebuilt locally. If you have an issue you go back to the shop.

You're probably better off taking the loss and using your Monster core to a local rebuilder.

Well, right now, it's junk (i.e a core.)

How much is your expense to ship to them and get it back?

You would then have a rebuilt by Monster Transmission for the core cost plus the expense.

Then, can you sell it for more than that? If so, you make a profit. If not, you don't.

And as you said, how much hassle for how much profit?

It's looking like about $600 total for shipping, repairing and return. Not profit. I'm already out the $2K I spent for it originally.

Re: What would you pay for 4L60 Monster Transmisionn fresh rebuild?

Consider the $2K a sunk cost that is gone (not gonna recover that.) The profit is on the parts you have left.

I just did a quick craigslist crawl, you can pick them up used in this area in the $150-$300 range for "worked when I pulled it" type deals. So, consider that a core cost.

So, say you could get $200 for it. That means $800 is your break even point if you were to ship it back and have it fixed and then try to sell it.

If you think you could sell it for more than $800, you're making some money... Question still is whether or not it is worth the hassle.

This kind of thing is what I fear with the TCI streetfighter 700r4 I just put in my '67. Rated for 750HP... We'll see after 90 days behind 625 ft/lb. So far I like it...

I WOULD NOT pay anything to anyone for any reason for any kind of automatic transmission.

My preference is to throw all auto trannys in the river.

Open it up and if it has any "special" parts in it save or install them in the trans you have now or put them on a shelf, I'd be pissed

Can you elaborate, are you just a “stick” guy or what are you saying, nobody builds a good auto transmission?

An $1,800.00 4L60e transmission will have nothing special in it. Proper and well built automatic transmissions from a performance transmission shop should cost several thousand dollars. Performance automatics are a purchase where you get what you pay for.

And always have your unit built by a shop within driving distance.

my stock 4l60e started slipping within 1000 miles. Had it rebuilt in Abilene. By national transmission a local guy but he builds them for drag and high hp/tq street vehicles. I had asked around town and glad I did. I looked at the Monster brand and did a lot of reading on forums. It seems to risky to purchase a internet transmission what’s the recourse if you can’t drive to them and “talk” about the poor quality of work.

Re: What would you pay for 4L60 Monster Transmisionn fresh rebuild?

I build my own automatics and only have had converters fail, B&M, Boss Hogg, TCI and 1 TH350 sprag that broke but I did not let it warm up and the vehicle had sat without an engine for 2 years..That one was my fault.

All GM standard shift 4 speeds I ever stuck an engine in front of Died a terrible death.
I never build a stick shift trans because the guts were all blown up. I had no idea where all those bearings and parts went when i dumped them out of the case.

Just head to the salvage yard and get another 4 speed.

Automatics are not that hard to build. You must pay attention to wear marks and patterns and know where each part goes.

Get some books or videos and learn to build your own.
I used to pay $12 for TH350 cores.
Recently got two 2004R's for 100 each with extra boxes of parts and included many valve bodies.

Cores now days are high.

Re: What would you pay for 4L60 Monster Transmisionn fresh rebuild?

you say it was shifting erratically and then slipping,in 5 miles i don't see frying any clutches.more then likely its electrical in nature.could be something as simple as a shift solenoid or the internal wiring harness,or bad connection at the pass thru.pull the pan and see if there is any crap in the pan.5 miles it should be spotless

I'm an old time, old school, old muscle car 4sp person. I like to DRIVE MY cars------------------I'm NOT a cruiser. Furthermore, I prefer the total control of a manual transmission-------------------it changes gears when I WANT it to change, NOT when it thinks the time or moment is right for a gear change. And there are other features of a manual tranny over an auto tranny. For example, you can push start a car with a manual tranny, you can't do that with an auto tranny car. If you are trying to line up a timing mark on the harmonic balancer at an exact spot, you can put a manual tranny in 4th gear (or 5th, etc) and gently rock the car (forward or backward) to move the crankshaft for lining up a timing mark. It is virtually impossible to do this with an auto tranny (must use the starter to bump the engine---------------WHICH CANNOT BE DONE WITHOUT ELECTRICAL POWER, and invariably it bumps too far). No need for routing and plumbing cooling lines for transmission fluid, and invariably having tranny fluid pour down your neck! NOPE, as far as Tom Parsons is concerned, auto trannys should be illegal. I hate 'um!!!!!!!!!!
