cod 116 #1 Posted October 17, 2013 Looking for information as why my 418-A starts to slow down down when mowing uphill and tends to speed up going downhill. I keep the tranny fluid within the crosshatching of the dipstick and cleaned all the fins on the tranny to try and keep it cool but invariably I have to ease the hydro lever forward to get the beast to the crest and then move it back to its previous position or further if I'm heading downhill. I realize it has 26 years of wear and tear on the tranny but I'd like to hold out hope that it's not going to stop working in the near future. Some of the other things I've done to try and see if they solve the problem is replace all the hydraulic lines and the cam plate. While changing the cam plate I did notice that the cam itself is worn and I intend to make a new one later this year. The PO told me that he'd just changed the tranny filter and oil just before I bought it ( May ) and I've been running 10w30 motor oil for tranny fluid and I've thought of switching to10w40 to see if that could help but I'm open to suggestions from any of you who've dealt with an aging hydro. Thanks in advance - Cod Share this post Link to post Share on other sites
SousaKerry 500 #2 Posted October 17, 2013 Sounds normal. Some of them tend to do it more then others, but this a common problem. If you do some digging you will find several topics on this with the Eaton trannys Share this post Link to post Share on other sites
dcrage 621 #3 Posted October 17, 2013 (edited) My 418-A does the same thing -- As Kerry pointed out there have been numerous identical topics started over the last couple years with no concensus answer I guess if we had Matt's foot control on these tractors we wouldn't notice this problem -- We would just adjust the "accelerator pedal" to get the right speed Edited October 17, 2013 by dcrage Share this post Link to post Share on other sites
squonk 38,989 #4 Posted October 17, 2013 I would buy a new cam and plate instead of making one and switch to syn. oil.. Marvin's tranny slowed bad after getting warm. I replaced the 1100 with another one and now the speed is constant. Share this post Link to post Share on other sites
leeave96 487 #5 Posted October 18, 2013 It is normal for the Eaton 1100 to speed up and slow down on hills. I live on hills and dealt with that for years. The only real cure is Matt's foot control kit. It really is the missing link to bringing these old iron hydros into the new century. Good luck, Bill 1 Share this post Link to post Share on other sites
