IIRC, Patton put a hold on M-26s from replacing Shermans because they were too heavy to cross pontoon bridges. Doesn't matter if you have a gas or diesel engine, if a 88mm or 75mm from a Tiger or Panther hits your Sherman, you are out of comission. What a lunatic (Patton).
If you can't get the armor accross the bridges to get into combat, they are totally ineffective. Rivers were a fairly significant obstacle in Europe. That is, if you want to believe that is why they were kept out of combat. The 88 would penetrate the frontal armor of the M26 as well. On the other hand, the M26's gun (90mm) could penetrate the tiger as well.
The M26 was blooded after an emergency call by the Army General Staff. All available M26's were ordered to Europe to get them into the theater ASAP after the experiance in the ardenes. Twenty tanks, all that were available, were shipped to Europe in January of 1945. By the beginning of February they were issued to the 3rd and 9th Armored division.
In short, they were not available for general use until too late in the war. On the other hand by August 1945 2,435 had been built. Some saw action in the Pacific and there were being staged in prepararion for the invasion of Japan.
