I have a 93 2wd 5.7. When driving on the interstate at 60 to 70mph, when I hit a bump in the road trans downshifts from OD and most of the time will shift back to OD but not always. And sometimes just keeps going back and forth in and out of OD. Any Thoughts, Thanks

2000 model 1500, Has no problems going thru the gears, but when it gets thru Overdrive and between 40-55mph tacking 1500rpm or so it will constantly change rpm by 200 up and down like the torque converter hits the final stage then changes its mind back and forth . Once you get above 55 it doesn't do it and runs fine. Does the truck have a locking torque converter? Can you adjust it?

Replying to: mdsxs4 (Sep 29, 2007 3:57 am) Time will tell, and if that happens to me I'll post. I'm not loyal to any car maker, esp. Toyota after numerous problems, service, & recalls I've had with them. The term "lost the transmission" sounds sort of vague. What does that mean? What was the problem? BTW, the 07 has been out less than a year and you have in excess of 36K miles??? Do you ever get out of your truck? Sounds suspicious to me. Tundra is having trans problems too, in addition to other problems. Read the posts. Out of the frying pan, into the fire... 1offroader

When you are refering to your 2007 please let the readers know if it is a 2007 classic or the 2007(new body style). My tranny problem was at 7k miles on my 07.

Replying to: fgr8frk (Sep 27, 2007 8:21 pm) What I did was add a qt. of Lucus transmission oil to help clean sticky valves. it did help, but it still does it every couple of months. Just stop turn it off let it sit awhile and works ok. ????????????? who knows. |
