Some cutting may be required
I have installed 4 of these coolers on trucks one 2wd and three 4wd I didn’t have to do any cutting on the 2wd but I did have to cut the bottom outside corners at a 45 degree angle on the top brackets. After that, everything was perfect.

7.3 Mishimoto Transmission Cooler
I debated whether to purchase this cooler or an OEM 6.0 cooler. I am VERY pleased I chose the Mishimoto cooler which is cheaper than the OEM especially after obtaining the correct step fittings from 1/2 to 3/8 line. Transmission temperatures are drastically lower and in check within the proper operating range for the transmission fluid. Installation was much easier with the radiator and intercooler out of the way. Because this cooler is now shipped with the updated hoses, the routing will need to change specifically on the passengers side to make everything fit and flow without restriction. The only thing I would change in the design would be to bend each hose barb 90 degrees toward the passengers side of the radiator support. This would make the fitment of the hoses much cleaner like the OEM cooler. Exceptional design and construction! Very nice product!

Cooler
This is a very well built trans cooler with everything needed for a 7.3 super duty. For the money it’s better than the 6.0 cooler swap. Keeps trans temps in check in all situations.

Impressive Product
Brand New built 4r100 with a decent aftermarket cooler was still hitting much higher temps than I would like.. Extremely impressed with the robust build quality, straightforward installation and excellent performance of this one. Hot day out? Bad traffic jam? Heavy load? All three at once? No problem. Performs so well I may need to put a piece of cardboard in front of part of it in the winter! Also has a serial number and lifetime warranty. I've put close to 10k miles on this one so far in various conditions, would buy again in a heartbeat.

Excellent Fit
This is the cooler to get. It fits perfectly especially if you follow the YouTube installation video. The hoses are also a perfect fit. I highly recommend this cooler

Mishimoto Trans Lines
Cooler is great. Hoses are crap. Blew hoses after John Wood transmission installation. John did not install trans but his guy here in Vegas did. didn't take long for hose to blow. Maybe 5000 miles. If you choose this cooler don't use the supplied lines. Neither John nor the installer were happy about the lines. Luckily I shut it down quickly or I would have been looking at a big bill.
