pressed o/d button but I didn't. also when come to a stop with my foot on the brake the tran feel like it skip before come to a complete stop. has anyone had this problem . THank

Hello-

Sounds like it could be more of a problem with the brakes than transmission.
Try this test - as your doing your 55-60 on the highway and you feel the van begin to slow down - gently put the transmission into neutral.
If you resume speed then your right - it's in the transmission. If on the other hand you continue to slow unusually fast then it may be an issue the brakes.
I had something like your describing happen to me - and it turned out to be the brake booster.

Good Luck
Glenn

Thank for the info is there anyone who may had the same problem.

When you release the accelerator, your rpm should drop immediately at 1000rpm or less. If it's more than that, it's something related with the powertrain system or PCM.

If it drops, it could be the brake, a misalignment in front wheel or a bearing.

man thank i do need the front wheel alignment on my van I'm going o do the alignment
check out rest Thank again.
