2000 Mustang Transmission slipping

[duheb]

I have a 2000 mustang 6 cylinder with 135,000 miles. The transmission slips terribly until the engine is warmed up, then it seems to run ok. This is particularly a problem on cold mornings where it may take up to 15 minutes of running before the slippage stops. I just had the transmission fluid changed and the system flushed out. I've also had sensors replaced but nothing has helped. What are we missing???

You need a Transmission rebuild.

Why does it work when warmed up you ask......... Heat expands metal and that is why when it gets hot it shifts OK. One day when it is hot it wont shift anymore.

Rebuild it now before you do any more damage to anything else in the Transmission.

Good luck.
