99 7.3PSD - 4R100 Transmission - Help!

[Uncle_Frank]

Hey y'all -

New to this website, but not new to the PSD! Having a couple of issues with my automatic 4R100 transmission.

1) When I drove to work this morning, the transmission was stuck in first gear. I would have to rev the motor, let off, and then get on it again to make it shift to second gear. I pulled a PO732, 2nd Gear Incorrect Ratio when I checked it.

A call to a local transmission shop says this is a mechanical issue, and something that has to be replaced with a newer part as Ford no longer makes the part due to its large unreliability in these transmissions.

For $2500, they will rebuild the transmission, including the part I need. (Rebuilding, they said, to handle the power by adding Bully Dog shift kit, better water flow system, new billet torque converter)

This worth it? Any other options that might help me spend my money better?

2) My transmission does what I call "free wheel" down hills. This is especially bad when Im towing down hill. What it does not do, if your confused, is literally release and I just roll free, the motor does not brake my truck at all.

Is this normal for my year and transmission? Is there anyway to keep the torque converter locked up to make the engine slow me and the truck down large grades?

Thanks in advance for your help. You guys rock!

They are correct about the bad part, Yes that is a reasonable price. What is the warranty??
The freewheeling down hill is a blown coast clutch piston. It is replaced as part of the o,haul and is quite common.

If they say the warranty is 12 mths 12000 miles,(very common), then say. If you're doeing all this, then the transmission should be better than stock, right? They will agree. Then you shouldn't have any reason not to warranty it for 2 years, would you? You might get double the warranty>>>

Thanks for replying -

I just got the truck back from the shop, and they have fixed my problems, as well as installed the upgrades.

As far as warranty, I got the typical 12 months, 12k miles. But, the shop is really cool, and if I have any problems, they said to call. I will keep the forum updated with this shop.

More posts on the upgrades after a few weeks for my review of them.

Thanks
