Hi ballofwa,

this is a possible issue with your Dog Clutch or your gear selector. The dog clutch is a sliding selector mechanism which is splined to the output shaft, meaning that its hub has teeth that fit into slots (splines) on the shaft, forcing it to rotate with that shaf. now if this is worn off, there is a tendency that it may not hold the gear selector in place leaving it it going a gear down or on a specific gear. you may want to consult a friend who have done DIY on the truck else a professional mechanic will pin it down and have it repaired.

You may also want to change your trans filter.

hope this helps.

regards

voodoo

TRANSMISSION


Fuse # 20 or 21 gets power through ignition. This fuse controls PRNDL indicator, speedometer, tach, & will cause transmission to not shift gears correctly. Ours took off in 3rd gear when put in Overdrive & only ran in 3rd gear. If we tried to manually shift thru gears (auto trans), it had 1st, 3rd, reverse. No 2nd or over drive. Replaced ignition. Fixed problem. Root problem was Electric motor that engaged 4 wheel low side was bad. Every time we used 4 Low side it threw power surge through ignition & blew ignition out. Good Luck.

I have a 1990 GMC Suburban. The transmission is slipping. I still have reverse, 1st, and can manually shift into second. No 3rd or overdrive... it just slips. What should I look for?


is it a 4l80e electronic shift transmission....it may be an issue with the solenoid pack...you can take it to someone who has a scanner tool for the trans...if it is indeed a 4l80e

My 1999 chevy suburban slips and doesnt go to 3rd geer do i need a new transmission


sounds like the bands are slipping or the worst case the sun ring gear has broken, in either case a rebuild is necessary. Have you tried changing the filter and fluid to see if this helps? This is a littly costly for the fluids and such but I would at least get an estimate fron a transmission shop, they might get lucky and find a bad selenoid or vacume line.
