Are you talking long 'overlap' upon shifting or a long period of time it takes to wind out a gear? VB's do not become 'dirty' to the point of becoming inoperable without some other underlying problem. So yeah, it could be worse.

You must be very detailed and specific when asking technical trans questions. In other words, help us help you.

Mileage?
Fluid condition?
Towing?
Preventative maintenance performed?
Modifications?
New noises?

like i had said trans was rebuilt 2 feb, ago and I think the guy made it shift this way so not to burn it up. as i have seen said about o/d , it will shift from 1 to 2 ok then if there is not enough speed it will hold in 2nd or if let off the gas it will nutarlize it self kinda, If I punch in to kinda then it take longer to shift O/D wont kick in till bout 50 to 60 more 60 1 mech friend said possiblle a peace of dirt type could be in the V/B making it stick. have not changed fluid or filter yet thinking of doing this soon real soon. it has been like this since i got it back, iwas also told that I welded both ends of trans when it went out..

From what I can decipher, it would appear to me that your throttle valve cable is a few clicks too tight. If this is a rebuilt trans from another vehicle, maybe the governor was for another rear gear ratio and needs recalibrated.

The TV adj. is easy but the gov recal requires springs and/or weights to be swapped out.

Read this.

OK now you got me thinking, since I dont know sqaut bout trans, and my guy is no longer avalible to me i have turned to friends to help me out , since im now laid off since 1/12/09 money is real tight , you mentioned gears ? since ive got the burban i hav found out it was in a good wreck not only front end also rear,, Rear end is out of a junk yard, still has yellow markings on it,, Im wondering now if it is the wrong gear ratio,- But b4 trans went out on me it ran great worked fine i was happy...( The day it went out I had punched it to the floor and took off like a bat out of hell and drove maybe 3 miles came to stop light and stopped felt trans chugg i baby it home 1mile away on back streets and found out i only had a slight forward and no rev,.) now ill ask for help agian what is the ratio i want to have (factory 1987 350w/tbi & loaded) in both rear's ?, and then what is the ratio i want with the 33's x15 x12.5 street mud/snow tires im running now couse i would go to 35 tall if it wernt for gas prices. TV cable will be easy couse we adjusted it to get it to shift sooner so ill put it back to factory and try, if not maybe get a new cable. DAMM i forgot we adjusted the cable i think 2 clicks out to get it to shift sooner i dont think it made a real damm in shifting some yes, shifts did come a lil sooner but said the hell with it, thinking something blocking in V/B ? and maybe would blow thourgh but it didnt ..SORRY forgot that lil tidbit,, that was bout 3 months ago and just been dealing with it.
