4l60e transmission no forward gears only reverse

I been looking everywhere for in formation on a 4l60e on my 2001 GMC Yukon if I put it in drive nothing no shifting in reverse it’s fine now if I put it in 1st manually I can shift up to 3 third till I come to a stop and start again in 1 st gear?? Anyone else ever had this happen?

Sounds like a forward sprag issue

Time for a trans overhaul...the forward sprag has failed...common issue...it is overridden by placing the trans in 1st....

You will not get 4th or overdrive...

Have it overhauled and if necessary upgraded....
