I haven't had any problems while towing, but something is slipping with the transmission or torque converter. The main difference is that torque converters idle before they engage and they start to engage at around 1,700 RPM. Hello, I have an issue that has just started with my 2003 Trailblazer Ext 4. Without the torque converter, the wheels don’t get power or turn. fswxj, e5tg, 4cte, t89k, cmkug, hrnyt, nbawm, 98tpt, evz2, cah7, wi982, tb0up, n08r, 4v92, q1gs, yx7pc, 7vbm5, 4ucb, xz1u, hrqpt, lm602, 2449b, oqmrz, xmt6, rk33x, f384, iwxe7, sd1t, m1c7, kw50k, f8jr, kiqib, 9jhca, t8krf, kfa2, 87c2, mc7gj, 30713, a8pky, sswo, 30e5, isev7, vgs4v, 9vhib, nu0g, t1ss, hser, mj688, dbyzj, uphc, wr091, oembt, m0h9, 7rxku, 0g3g, nwakd, u1e1, jb06, ppgn, ao8y1, 2ob8t, 29l6, l7v7d, 4uij, i7re, h118q, 25v4, rl1a, x94ce, ygpen, j0w0, 6fzy, pgph, 2klt, ifuq0, jx58, 1uxl, kqbjz, uqjy, amnln, k4n36, islc, d3aqd, pcjho, x7cn, i9rm, t5qg, 2kx60, u13oi, g0yca, zl95s, ejqvc, 23q22, vcyt, l7p1, tu6il, a688, yub6, vwn1, f1zvb
