1987 s-10 blazer transmission

[barjac]

our 87 blazer runs great ,but once it warms up the transmission stops working.it works fine till it warms up.this transmission has been rebuilt while in another blazer.hope you can help!

[BlazerLT]

please be more specific with the problem.

no working tells us nothing.

It won't move at all.it acts like it's still in park.when it cools off again it works.

[BlazerLT]

Has the transmission ever been serviced with new fluid, a flush and a new filter?

[barjac]

it's been a while.my husband said he is going to try that.

Yip, should help.
