• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

72 Scout Manual Tranmission power lose at takeoff

Hi guys,
My transmission has started losing it pull on taking off from a stop in 2nd gear, 3rd and 4th gears the engine revs high but doeant seem to have much pull. However once I'm up to speed it works fine.
I have no grinding or sounds from the Tranny and it shifts fine. I do get some smell the longer I drive it though.
I recently changed the trannu fluid with a GL1 90w but it didnt seem to have any effect.
I would appreciate some advice as to what could be the problem, clutch, tranny itself etc.



Sounds like your clutch is slipping.
Do you have a tachometer? If so, does it show the engine revving without an approbate increase in vehicle speed?
Can you make a video (& audio) of this happening and post it up?


You should pull the inspection plate off of the bottom of the bell housing, which allows you to see the throw out bearing. With the clutch pedal out, it should not be in contact with the clutch fingers. You should be able to move the throw out bearing in and out a little with only the clutch pedal return spring giving any resistance (engine not running). If you are lucky all you need to do is adjust the length of clutch adjusting rod that goes through the floorboard. Did you recently do a body lift of any kind? Another indicator would be if you have no free travel of the clutch pedal before you feel any resistance from the clutch.
