I have a question about an 98 Accord EX coupe 4 cyc with a auto 4 speed BAXA. I rebuilt it, to include the valve body. I cleaned the bores with the bench buddy brushes, replaced the Converter charge pressure reg valve with the Sonnax part number 98892-04K, Also installed transgo LK2 lube correction kit, the end plugs on the valve body were replaced with Sonnax o-ringed end plugs kit 98892-01K. The TC was also replaced.

My issue is around 1700 RPM, I have a flux of 100 to 300 RPM between 35 to 42 mph, and if I accelerate a little it goes away. Also when stopping the trans shifts hard into 1st. If I come to a slow stop, it is hardly noticeable.

Any ideas, Thanks

Are your pressure numbers within spec?
Have you called Sonnax or TransGo in regards to the 1st gear engine braking?
Mixing and matching two different companies improvement kits may net you an undesirable characteristic. Not every company shares the same thought process on how to fix or improve on a hydraulic circuit.
Some shift kits, depending on how they are setup, can cause an early 1st gear engagement rather than coming to a stop in 2nd. Have you tried shifting into 2nd on deceleration to see if it prevents the 1st gear downshift?

I haven't called sonnax or Transgo. Have not checked pressures yet. What gauge set-up is required for the PSI check? I noticed this morning the 1st gear down shifts were normal(not noticeable). After about 20 min of driving, normal temps it started again. I have tried manual down shifting with the same results, smooth until at a stop then pulling it into 1st.
