Thanks, I pulled of the top and your correct about the gears, I also marked and turned the input and the output outran it , then dropped 1 gear ( direct) and it was 1 to 1 , And yes the TRDX will have a super low 1st gear, it took 12 1/2 turns on input for the outputs 1 turn ! Thank y’all for the advice! I’m going to use it In the LJ

Thanks for the help, I was hoping the only difference in the TRD & TRDX was lower 1st gear, .77 OD sounds great, I’ll pull it out of the parts truck next week! Thank y’all

I have a 1951 LJ , it came new with a TRD-150 Trans , It went out back in the 70s when we still used the truck, we put a 10 speed direct in it , the original trans was probably hauled off for junk , I’m restoring the truck and while I have the cab off I want to put a TRD-150 back in it just for the overdrive, I have a LJ parts truck with a TRDX-150 , I have read these have lower gears for dumps or cement trucks ( this parts truck was used for house moving ) Does anyone know if it is still a overdrive , like the original TRD-150 ? Thanks Dean
