Fortin 4spd h pattern w/ converter


Well-Known Member
new car and new to me 4spd with converter set up. Jamar xp shifter. With the car on stands it shifts good. While driving like up and down the street of I stay very low rpm below 2k it will shift fine. But if i drive more aggressive I can’t get it to come out of the gear it’s in.

Friends have told me I have to let the converter unload before shifting but i can’t believe I’ve got to let it go all the way back down to 2k rpms before it will let me shift.

I’ve never driven a converter transaxle set up. Any advice?

Make sure to lift before you try to shift. Also take a very good look at your shifter and the entire linkage. If there's any slop there, it will cause problems.
