Reverse is gone

[Standstrong]

when i put it in reverse i have to give it gas and the whole truck shakes. 2005 f350 drw 6.0. I bought the truck last Aug, and the warranty on the powertrain is voided due to the previous owner / idiot.

Check fluid levels. Any programmers installed? My old Edge tuner had a lunch buffet on my transmission, and i ended up with the same symptoms (shaking in R, having to give it gas to move) before it finally gave up the ghost.

Also, i had a Tran. cooler line with a pinhole, and the two situations coincided to me building my trans right.

Edit: there was also a TSB on reverse snaprings, but it does not apply to your truck IIRC

My fluid levels are fine. SInce i have owned it i havent put any mods on it. But Im assuming the previous owner might have which resulted in the warranty being voided

[Standstrong]

well everything is getting worse, i dont know what to do

got the same problem bud. is it running real high rpm in like 2nd and 3rd gear now too? ima watch this one and give ya a bump.

[Standstrong]

yea its shifting really hard now.

ive added a quart of gear oil from a tractor, its a lot thicker than trans fluid...that and 2 quarts of trans fluid and its doing better. trucks at home but im waiting to get home to decide to dump more trans fluid in or to drop the pan check the filters and the fluid itself and do a flush.
