Transmission Ice Blasting
When people call about transmission, the constraint is usually the same. We clean it without water, without chemicals and without anything abrasive touching the surface.
What builds up, and why it matters
On this kind of work the problem is baked grease, road film, undercoating, sound deadening, adhesive and brake dust. Media blasting will cut into aluminum and pit a frame. Pressure washing drives water into looms and bearings. Solvent strips the finishes you wanted to keep. Dry ice takes the contamination and leaves the part.
Engine bays, frames and undercarriages are cleaned on a lift, on stands or in your driveway. The people who call us about transmission are usually restorers, shops and owners who actually care about the vehicle, and the thing they are actually worried about is damage to a car that took years to put together.
The method
Why dry ice and not the alternatives
- Non-abrasive
The pellet is soft and sublimates on impact, so the work is thermal rather than mechanical. Machined faces, plating, paint and gaskets survive it.
- Low moisture
No standing water in a harness, a bearing or a cabinet, and no dry time before the equipment goes back into service.
- No secondary waste
Sand, soda and walnut shell all have to be swept and hauled. Dry ice leaves only the contaminant it removed.
- Often no teardown
Much of this work is done in place, which is usually where the real saving is. The labor is in the disassembly, not the cleaning.

Questions we get asked first
Will it damage the surface underneath?
On most substrates, no. The pellet is soft and sublimates on impact, so it does thermal work rather than mechanical work. We still test an inconspicuous spot first on anything unusual.
Do you have to take the equipment apart for transmission?
Usually far less than you would expect, and often not at all. Cleaning in place is where most of the saving comes from, because the labor is normally in the teardown and reassembly.
How much mess does it make?
Far less than the alternatives, because the blasting media disappears. What is left is the contaminant itself, which we contain and clean up.
Do you come to us?
Yes. The whole rig is mobile. Compressor, hose and operator arrive at your shop, plant, driveway or dock, anywhere across South Florida from Miami out to roughly a hundred miles.
What does a job cost?
It depends on the equipment, the contaminant and the access, so we will not throw a number at you over the phone without understanding the work. Describe the job and we will give you a real figure.
How soon can you look at it?
Send photos and a short description and one of the owners gets back to you. If you have a shutdown or a deadline, say so up front and we will tell you honestly whether we can hit it.
The comparison
How this compares to the usual methods
- Solvent and degreaser
Trades the deposit for a residue, plus ventilation and waste to deal with, and it is hard on the finish.
- Hand scraping
It is the fallback when nothing else is available, and it shows on the surface afterward.
- Media blasting
Cuts into the substrate by design. Fine on structural steel, wrong on aluminum, plating, machined faces or anything with a tolerance.
- Pressure washing
Pressure pushes moisture past seals and into connectors, and then you wait. Panels and motors rule it out.
- Dry ice
Thermal shock breaks the bond. The pellet sublimates, so nothing abrasive touches the part and nothing is left to collect but the contaminant.
What comes off
The deposits we see most
Most calls involve one of the following. The common factor is a bond between two things that should not be bonded.
- Adhesive and sealant
Whatever the last repair left stuck to the mating face: gasket, sealant, deadener or adhesive.
- Resin and mold release
Release agent and resin build-up on tooling, where a solvent fix trades one residue for another.
- Paint and coatings
Selective removal, layer by layer, on parts where media blasting would cut into the substrate.
- Salt and corrosion product
The year-round problem on the coast. The finish holding corrosion back has to survive the cleaning.
- Ink and printing residue
Dried ink and coating build-up on rollers and press components, where the surface texture is the product.
- Food residue
Burnt-on product, fat and sugar on processing gear, with no chemical residue left on a contact surface.
- Grease and oil
Oil film is the layer everything else sticks to. Remove it and half the job is already done.
How a job runs
What happens once you call
If you have not seen this done before, the process is worth reading once. Nothing below is hidden in a footnote.
- We look at access and containment
Siting the compressor, masking what must not be touched, and catching what comes off, settled before the first pellet.
- We test a small area
Pressure and pellet size get dialed in on an inconspicuous spot before we touch anything visible. Painted parts, soft alloys and older finishes all behave differently, and the right setting on one is the wrong setting on another.
- We blast, then clean up
The ice is gone the moment it does its work. What stays behind is the grease or carbon that came off, and collecting that is part of the job, not an extra.
- You look before we pack up
We would rather you find the missed spot while we are standing there than a week later. Another pass on the day is the cheapest fix available.
- You describe the job
Tell us the machine, the mess and the constraint. A couple of photos answers more than a long description, and if the honest answer is that something else suits it better, we say so.
What happens in your space
Masking happens first. Whatever is adjacent and vulnerable gets covered before the hose is picked up.
Dry ice is carbon dioxide in solid form. It is non-toxic and leaves no residue, but it does displace oxygen in an enclosed space, so ventilation is part of the setup rather than an afterthought.
Expect noise. Everybody inside the working area wears hearing protection, us included.
Cold surfaces are the one aftereffect. Depending on the piece that is either a few minutes of patience or some condensation while it returns to room temperature.
Tell us what needs cleaning.
Give us the job, the address and a rough description, pictures if you have them. The call back comes from Giancarlo or Kenny directly.
