After having the truck for over a year (shifted fine the whole time) I started to do alot of towing in the mountains. The first time I pulled a heavy load up a 18% grade I made the mistake of not pulling it into 1st gear,just had the selector in 2nd. When it started to drop to 25 mph I pressed the throttle to the floor & it downshifted & then up shifted real fast about 10 times till I caught on & left off the throttle(yea,I'm abit slow ;D). Now when cold w/o a load or with a load it kinda shorts shifts & has to much slippage/overlap. Did I screw up the trans for good or should I do a trans service??? Sorry so long but I'm ??? ??? ???

 

I can't help you concerning where you messed up your transmission or not, but if it is still working alright after that you must not have done any damage.<br><br>I must ask the question where is this 18% grade?

 

Has it ever been serviced? If not, try changing the fluid, filter and adjusting the bands.<br><br>Also interested in the 18% grade... ;D<br><br><br>Tony

 

It's a hill in Pa. going up Rickets Glen. Just when you think your doing fine it adds that extra little &quot;bump&quot; to go over. It's about the only way to get to our property &amp; I have a trailer &amp; truck bed that just needs to be filled up.

 

Ok thanks for the hill info.<br><br>I would agree with TPilaske about changing the fluid if you feel that it came close to overheating. Some others will surely reply.
