code P0751 and no OD

[minivan_owner]

hi all, i'm a new member. i have a 1998 olsmobile silhouette (same thing as a venture right) and i have a code P0751 that set the SES light. i went to autozone and they told me something was wrong with a solenoid in the transmission. would this account for having no overdrive? everything was fine until a tranny fluid/filter change.

thanks for any help. i hope this isnt anything major

ok i found this information on the web
http://www.gm.com/company/gmtunersou...ansmission.pdf

if you scroll down to page 13 it shows the shift algorithm for the 4T65e.

code P0751 according to autozone is

The PCM has determined that the voltage signal from shift solenoid "A" indicates inadequate performance or a "stuck off" condition.

could replacing this solenoid A fix my problem? according to that website it only comes on in first gear and overdrive. i don't know what that means exactly but could the solenoid come on in first and stay shutoff after that? i have no problems from first to third gear. thanks for any help.

Most transmission shops will do a free scan of your transmission performance using a scanner designed for that purpose. The scanners Autozone uses are just a general scanner and aren't very helpful for the inner workings. My advice would be to take it to a shop and have them check it for free. Then go from there.

thanks for the reply cdru. just in case it turns out to need a rebuild, how much should i expect to pay? i know it depends on the shop, but what is a good estimate? thanks again cdru

after driving the van for a couple of days the SES light has gonne away and overdrive came back . i guess the solenoid unstuck itself .

[minivan_owner]

the problem came back . any idea how much it'll cost to have the solenoid replaced?

About 800.00 here in NYS for the solenoid pack.
