I have an 01 '50 5.4 2wd.

Just curious, do you guys know about how many miles the average 01 trannies will last?

I should mention at 100k.. I flushed everything with BG flush and replaced with royal purple equivalents.. specific to tranny I dropped pan, flushed with bg and replaced fluid and replaced filter.

Have about 120k. Don't notice any problems just curious..

Hoping to get at least 200k before a replace... with easy "adult" style driving. IE. No power braking, spinning tires from every take-off and minimal towing.

No Royal Purple jokes please.. be serious....

Cheers and

Edit: What tranny does the 01 2wd 4sp '50's have?

 

it should last 200k some peoples last 300k if you continue to take care of it it will last a good long time.

 

It's a 4R70W, do NOT use that BG flush again, and we have 2 professional transmission rebuilders here that specifically do NOT recommend Royal Purple in a 4R70W.

 

I haven't noticed any problems with it so far like stutters, stalls or whatever. Seems to run just as usual.

 

op, do you let your truck idle in park alot?
