I have just finished a rebuild of my CL's transmission which is a M7ZA. Car has 105,000 miles and has been treated well since I have had it. 7 years now. Transmission started having typical flares and then slipping and banging from 1st to 2nd after driving for approximately 20 to 30 minutes. Before it warmed up it would shift fine and not slip at all. I figured that it was do for a rebuild due to the typical burnt second clutches and clogged filter. I disassembled, thoroughly cleaned and inspected every part and replaced frictions and steels, bonded pistons and all sealing rings and o-rings. I took my time (4 days) to understand and fit every part together several times before final assembly. I cleaned valve body and purcased bench buddy brushes and made sure everything worked smoothly. I installed a new torque converter and filled trans with 7 1/2 quarts of Honda fluid. I will shift into reverse, can hear gear engage, will hold, but slips if throttled. Shifting into D4 results in nothing, most times. D3 same as D4. D2 enages normally. D1 engages normally. Then moving selector to D3 or D4 sometimes engages normally. When I first pulled out of my garage, I drove it around the block in D4 and it shifted 1-2-3, then came to stop light and felt like neutral. I put in D2 and continued around the block back into garage. I did bench check and clean solenoids. Double checked all connections on solenoids, etc. Any thoughts would be helpful. Trying to figure out if there is a solenoid that would cause all these problems.
