Took it back this morning..the worker who installed it took a ride with me and agreed theres something not rite..He suspects its the new converter may have one gear compare to the orignal that has two, he said its the same part number but this new one is aftermarket...So he'* gonna compare.

Thank again.

Let us know what you find out.

Does it upshift through all 4 gears automatically?

It does shift but not like before rebuild,the shift are longer than sooner..They are ordering a new converter...i'm wondering if they put in a converter for a non-superchared bonneville..Well it will take at the most two days..I'll let you guys the results.
Thanks again!

Hey guys thanks for all the advise..I got the car back this pass friday the repair shop said the new converter was either bad or wrong application..He replaced it and I took it for good run today now it'* back to normal or even stronger..
Thanks again.

Good to hear that they took care of it! I had a hunch the TC was your problem!

Great news!
