I just stripped my input shaft on the converter side. I noticed that the input doesn't sit all the way in the converter could I possibly need a longer one? The shaft only stripped about 1/2"to 5/8" inch.

I don't know that you could find a longer input shaft even if you wanted to. Mark will be along shortly, but he's going to want some information. Was this the first time the transmission has been off? All original parts - original torque converter? If not, what parts where changed and by whom? What were you doing when it stripped? Pictures would be nice.

I wanted to upload a pic but wasn't allowed. When it happened I just turned right from a dead stop and one block down I lost all power. I found one I removed the tranny the shaft was stripped. I also found shaft that are 14 1/8 long and 13 5/8 long shafts. I don't know if it was original or not I bought the truck with 150,000 miles I have 200k now

Older ones are shorter . The longer one will have a ring groove id mark just below the splines.

Ok so should I put in a longer one so it'll sit all the way in the converter?

Do you know if it has a steel planetary that the shaft goes into? I have never seen a convertor strip the splines off the end of the input shaft. I have seen the planetary break where the shafts goes in(aluminum) this was why they changed it to steel and they also made the shaft longer.

Not sure but it stripped on the converter side and the shaft doesn't reach the end of converter.

I believe the converter is steel

Yes the convertor is steel I was referring to the planetary in the transmission. Can you post a picture of the input shaft?

Got a pic up. As you can see the input shaft just stripped about 1/2 from the end that's how far it reaches in the converter but I feel like that to little and should be the longer 14 1/8 shaft

Here is some info on that shaft.

Here is the correct measurement off of one of our stock units. This one will be going into a 2009 f250 6.4

I gotcha now how can I see if it's cast iron or aluminum?

And would that measurement be the same for a 99 with 7.3

That depends on if any body had the unit apart and did any changes.

See if a magnet will stick to it.
