Regear with bigger tires leading to incorrect speedometer and odometer

So I bought a truck recently that had a regear done to it. Not sure what the ratio is. Couple questions. How would I go about finding that ratio, and after I do that, how do I match my speedometer and odometer to my axle.

 

Here are the others if you dont have a 4 banger:

If I’m not mistaken that fixes a 1st gen

 

I thought that was a 1st gen solution only, no?

 

Beat me by less than a minute.

I need to do this eventually since I'm on 35s and regeared. Did my research and will be buying the hypertech, 6 cylinder truck. Just more important mods in front of the line.

 

Good to know, works on 4 banger 2nd gens as well. Got it.

 

Dig that video, thanks Ed. Looks like OP has his answers now. How to figure it out, and options for calibration.

 

I clicked on that toyotapartsdeal thing up there, it said not compatible with 2006 nor 2013 Tacoma. It never asked about 4 cyl., 6 cyl., MT or auto., nor any other info. Not sure but thought my 2013 Reg. cab, 2.7, 4X4, auto. speedometer got it's signal from a rear wheel sensor, or that's what I've been told. Would be great to get mine corrected by changing the little gear. That computerized stuff is just out of my league.

 

Shit just figure out how far off it is and let your brain remember, super cheap fix use your noggin.

 

problem is that if you ever go for resale the mileage won’t be correct.

 

Every now and then I read something on TW and I take a screenshot of it, here's one of them.
