R141f to R151f

[john_d]

Has anybody converted the R141f transmission into a R151f. What parts are required for the conversion?

i went the other way, R151 to the R141 due to the gearing. 1st gear is way too high for wheeling in the R151 but, as you know, the R141 has no O/D.
it is a straight bolt in...

what is the first gear ratio for each of them? I thought the R151 first gear was really low geared?

R151 4.313
r141 4.843

Thanks. What parts would I need for the overdrive and how much would it cost approximately?

you can not add the O/D to the R141... well not easily that is (if it can be done at all) i looked into this briefly when i had the first R141 apart...
want O./D then the R151 is the only real option, that being said there was a thread on here somewhere where a bloke was sticking a H55F behind a PZ...
