I think it was the TF-1 kit but remember this is a lockup converter valve body.......It has an S-bend tube on the top..... Even before I messed with anything drove the car with the stock 318 2bbl the trans would freewheel in 1 st gear. I remember it would not provide engine breaking in 1st gear but I thin it would if i held it down in first... it would freewheel when left in drive???? TBF



Might be an issue with the over running clutch ? The lockup convertor and it's fluid path should have ZERO effect on first gear operation .



Gonna have to agree with JohnRR on this, my trans is a lock up 904 and I got no freewheeling.

I think the free wheeling is from the low reverse band not applying in manual low and it should be applying with a TF 1 2 or 3 kit in manual and auto low. If reverse is fine then the band is functional and you need to figure out why it is not applying.

BTW I really like LU in a street car especially with a high stall converter
