Automatic Transmission - rebuild my trans local or not DFW

Looking for a reputable place to rebuild my 1994 4l60e trans. Looking for a warranty. Local prefferred but will pursue my best option.
Ive rebuilt this thing over and over the past few years and am just sick of doing it myself and overlooking issues.

Has the following parts in it:
.490 boost valve
Hardened rings in pump with high rev slide spring
billet servo 3nd and 4th
All pinless billet pistons
Wide kevlar band and drum
Rebuilt valvebody with transgo plate
stiff acc springs
caged roller sprag
alto red eagle clutches
vigilante 2800 stall and an external stacked plate cooler
Have been having issues with it since new motor install and havent even had a full throttle blast on it. 2-3 and 3-4 shifts are week and delayed no matter how much pressure i throw at it and will not take off in od or 3rd unless dropped down to 2nd or 1st. Now it intermittently loses 3rd and 4th.

This is a 3800 lb street car 70 chevelle with a estimated 600hp/tq turbocharged 6.0.
Budget is of concern so just looking for the best on price price.
pm me or email at lt170chevelle@yahoo.com
Thanks in advance.

I was talking to Gilbert @ ace racing in garland. He offers a 6 mo warranty.

I emailed Gilbert a month ago asking for a quote on my trans with all the specifics of what is in it and doing but never got a reply.. Garland would be very close for me.

I just emailed him again so hope to get a response this time. Thanks

Gilbert would be your best bet.

Keep in mind it's hard to keep up with PM's sometimes when you are in high demand. Give Gilbert a call and I'm sure he'll get you fixed up.

We do 4L60E's occasionally but we're so swamped right now I would rather send you to Gilbert.

Ok Gilbert emailed me back and he will be setting me up. Thanks again.
