Transmission-No Forward But has Reverse

Hey all, I need some help please. I have a hyster H50XL. I just bought it second hand. It ran well with no problems. I replaced both front brakes, wheel cylanders and Master cylander. I had noticed that the tramission fluid needed to be replaced, So I did. In driving it and testing the brake issue(which works) I started losing power. I have lost complete forward. It does have excellent bite in reverse though. I talked to mechanics at United Forklift and they told me that the transmission needs replaced. Can anyone give me any insite please on this issue. Anything I might have missed or that could help. I am very frustrated with this. Thanks in advance.
Also, if anyone has the mechanical drawings to this truck please let me know. I will buy them. Thanks again.

If you remove the large drain plug on the transmission (faces to the rear) Watch out for the spring (not too strong, but can catch you). If the clutch pack has failed, you should find metal shards, and dark chunks of clutch friction material in the suction screen(behind the spring). This type of failure can be very expensive !

Pushing with the inching pedal partially engaged, and/or the wrong oil can cause this failure (The oil spec is J20A or J20C)

If the clutch has failed, an exchange transmission is the best option...The shaft updates will add $$$$

Gregorash,
Did you find your problem?

I just bought an H60XL with the very same symptom. I have new clutches on order which should be here in the next day or two.

"Unicarriers - it would have to be for a dual fuel unit also. Usually a bad cam or crankshaft sensor will throw a E-27 or a E-28 code on the dash panel... If it does not light up and the bulb is bad then it will not start also."
